Settlement Rails & Proceeds Routing — Confirmed from Developer Docs, April 2026

Yes — every protocol sends USDC/USDT to any
address you specify, including custodians.

Centrifuge, Maple, Ondo, Goldfinch, TrueFi — every major RWA protocol ultimately settles in USDC or USDT sent to an Ethereum address. That address can be your Fireblocks MPC vault, a Gnosis Safe multi-sig, an Anchorage Digital custodial account, Coinbase Prime, or BitGo. You register the address once; proceeds arrive there automatically from every protocol draw. This page documents exactly how, chain by chain and custodian by custodian.

Confirmed from live developer docs (April 2026): Centrifuge v3 is live on 9 chains (+ Solana + Stellar); accepts USDC, USDT (BSC), and USDS (Ethereum). Maple explicitly lists “custody solutions” as supported integrations; syrupUSDC and syrupUSDT are both ERC-4626 with cross-chain CCIP routing to Solana, Arbitrum, and Base.

Protocol Reference

Custodian Integration

Six ways to receive proceeds at a custodial address

Each method below shows exactly how to register a custodian-controlled address with DeFi protocols — including the specific API calls for automating the flow from protocol drawdown to custody receipt.

Fireblocks MPCMPC (Multi-Party Computation)

Compatible: Centrifuge, Maple, Ondo, Goldfinch, TrueFi, Clearpool

dev docs →

Create a Vault Account in the Fireblocks console or via Fireblocks API v2. Generate a deposit address for USDC/USDT/DAI on Ethereum (or any target chain). Register this address as the issuer/borrower address when setting up your Centrifuge pool or Maple facility. All USDC proceeds from pool drawdowns are automatically deposited to this Fireblocks vault.

API flow

01POST /v1/vault/accounts → creates a named vault account (e.g. "DIGAU-Reserve")

02POST /v1/vault/accounts/{vaultAccountId}/ETH_TEST/addresses → generates permanent deposit address

03Register that address on Centrifuge as pool admin address or Maple as borrower wallet

04Incoming USDC triggers Fireblocks webhook: POST to your configured webhook_url

05Webhook payload: { type: "TRANSACTION_STATUS_UPDATED", data: { assetId: "USDC", amount: "...", destinationAddress: "..." } }

06Use Fireblocks co-signing policy to require N-of-M approval before outgoing transactions

Fireblocks is the de facto institutional MPC wallet standard. Used by Coinbase Custody, Anchorage Digital, and many prime brokers. Centrifuge, Maple, and all ERC-20 protocols are natively compatible.

Gnosis Safe (Multi-Sig)On-Chain Multi-Sig

Compatible: Centrifuge, Maple, Ondo, Goldfinch, TrueFi, Clearpool

dev docs →

Deploy a Gnosis Safe (now "Safe") at safe.global with your chosen threshold (e.g. 2-of-3 signers). The Safe's contract address is a standard Ethereum address — any ERC-20 token can be received without special setup. Register the Safe address as the Centrifuge pool issuer address or Maple borrower address. All proceeds arrive at the Safe contract and require multi-sig approval to move.

API flow

01Deploy Safe at safe.global/app — choose chain (Ethereum, Base, Arbitrum), threshold (e.g. 2/3), signers (Fireblocks API signer + 2 hardware wallets)

02Safe contract address is generated — use this as your issuer address on all protocols

03Centrifuge: set Safe as pool admin → all drawdown proceeds go to Safe

04To move funds: create Safe transaction → wait for N signer confirmations → execute

05Safe API: GET /v1/safes/{safe_address}/transactions for history, POST /v1/safes/{safe_address}/multisig-transactions to propose

06Integrate with Fireblocks as a signer: Fireblocks supports Safe via SDK (fireblocks-defi-sdk)

Gnosis Safe is open-source, holds over $100B in assets, and is the most trusted multi-sig on EVM chains. Zero custody fees. All DeFi protocols natively support Safe addresses — they are just Ethereum smart contract addresses from the protocol's perspective.

Anchorage DigitalQualified Custodian (OCC-chartered)

Compatible: Centrifuge, Maple, Ondo (whitelisted), Goldfinch, TrueFi

dev docs →

Anchorage Digital is an OCC-chartered national trust company — the only federally chartered digital asset bank in the US. Open an Anchorage custodial account, complete institutional KYB, and receive a dedicated Ethereum deposit address for each asset (USDC, USDT, ETH). Register this address as your Centrifuge issuer address or Maple borrower wallet. For Ondo, submit the Anchorage address for whitelist approval (standard institutional path).

API flow

01Apply at anchorage.com/custody — complete institutional KYB (entity, beneficial ownership, AML)

02Receive dedicated Ethereum address for USDC: unique deposit address per asset

03Register address on Centrifuge pool or Maple facility during onboarding

04For Ondo OUSG: submit Anchorage address to Ondo institutional team for KYC whitelist

05Anchorage API (institutional): GET /v2/accounts/{account_id}/addresses, POST /v2/transfers for outgoing

06USDC received → Anchorage auto-detects → credited to account → available for wire out to CIBC Bank USA

OCC charter means Anchorage is regulated as a bank — the strongest regulatory foundation for institutional custody. Used by major hedge funds and sovereign wealth funds. Can convert USDC → USD wire to CIBC directly.

Coinbase PrimeInstitutional Custodian + Exchange

Compatible: Centrifuge, Maple, Ondo (whitelisted), Goldfinch, TrueFi

dev docs →

Coinbase Prime provides institutional custody, trading, and financing in one platform. Open a Coinbase Prime account, complete institutional KYB, and get a dedicated Ethereum USDC address. Register this address on DeFi protocols. Coinbase Prime natively integrates with Fireblocks for sub-custody relationships. USDC received can be converted to USD and wired to CIBC Bank USA same-day.

API flow

01Apply at coinbase.com/prime — institutional KYB required

02Coinbase Prime API: GET /api/v3/brokerage/portfolios → find portfolio ID

03GET /api/v3/brokerage/wallets → get USDC deposit address on Ethereum

04Register Coinbase Prime USDC address as Centrifuge issuer or Maple borrower

05Incoming USDC auto-credited; webhook notification available

06Sell/convert USDC → USD: POST /api/v3/brokerage/orders with sell order; USD available for wire out

07Wire to CIBC Bank USA: initiate via Coinbase Prime portal (same-day for amounts under $25M)

Coinbase Prime is the most accessible institutional custody platform — no minimum AUM requirement at account open. Integrates Circle's USDC rails natively. Best option for platform launch phase before graduating to Anchorage/Fireblocks.

BitGo Multi-SigMulti-Sig Custodian

Compatible: Centrifuge, Maple, Goldfinch, TrueFi, Clearpool

dev docs →

BitGo uses 2-of-3 multi-sig (BitGo + user key + backup key) for Ethereum wallets. Create an ETH/ERC-20 wallet in BitGo — the wallet address is a standard Ethereum multi-sig address. Register this as your Centrifuge pool address. USDC/USDT proceeds are deposited to the BitGo wallet address and require 2-of-3 key approval to move.

API flow

01POST /api/v2/eth/wallet → creates a new BitGo Ethereum wallet (returns walletId and address)

02GET /api/v2/eth/wallet/{walletId}/addresses → get deposit address

03Register BitGo wallet address as Centrifuge issuer or Maple borrower

04POST /api/v2/eth/wallet/{walletId}/send → initiate outgoing transfer (requires 2-of-3 co-sign)

05BitGo supports ERC-20 tokens automatically — USDC/USDT/DAI all recognized

06BitGo webhooks: configure for incoming transaction events

BitGo is SOC 2 Type II certified and carries $250M in insurance per wallet. Older protocol than Fireblocks MPC but battle-tested. Good for backup custody or secondary reserve wallet.

Circle Mint (Business API)USDC On-/Off-Ramp

Compatible: All protocols — Circle mints/redeems USDC natively

dev docs →

Circle's Business API allows direct USDC issuance (wire USD → Circle → USDC on-chain) and redemption (USDC → wire USD). A Circle Business Account acts as the bridge between DeFi protocol proceeds (USDC) and the CIBC Bank USA wire account. Circle generates a unique wallet address per account; this can be the destination for Centrifuge drawdowns. Proceeds arrive as USDC → Circle converts to USD → wire to CIBC.

API flow

01Apply at circle.com/en/circle-mint — business account KYB

02POST /v1/wallets → create a Circle-managed wallet (returns walletId and address)

03Register Circle wallet address as Centrifuge issuer address or Maple borrower

04Incoming USDC detected; GET /v1/transfers to confirm

05POST /v1/businessAccount/payouts → initiate USD wire out to CIBC Bank USA (routing + account)

06Wire settles in 1 business day via ACH or same-day via Fedwire

07Full USDC ↔ USD conversion at 1:1, no conversion fee for Circle Business accounts

Circle Mint is the cleanest fiat off-ramp: USDC in → USD wire out at 1:1, same business day. No exchange spread. Ideal for converting Centrifuge pool drawdowns to USD for CIBC escrow deposit. Circle is the issuer of USDC — zero counterparty risk on the stablecoin itself.

Getting USDT

USDT access — direct protocol support and swap routes

Two protocols support USDT natively — Maple (syrupUSDT ERC-4626 on Ethereum) and Centrifuge (USDT vaults on BSC). For all other protocols, USDC received can be converted to USDT at near-parity using Uniswap v3 or Curve.

Maple syrupUSDT — direct ✓ confirmed in docs

Deposit USDT → receive syrupUSDT (yield-bearing). Redeem syrupUSDT → USDT returned to your wallet. No swap needed.

Platform Flow

How issuance proceeds route through the platform — start to finish

Six-step flow from SBLC issuance through protocol draw to custodian receipt to fiat off-ramp and eventual repayment.

SBLC Issued

CIBC issues MT-760 SBLC → anchored on-chain as ReserveProofAnchor.sol hash. SBLC serves as collateral for DeFi protocol access.

Protocol Registration

Platform registers custodian wallet (Fireblocks vault address or Gnosis Safe address) as issuer address on Centrifuge pool OR borrower address on Maple Direct facility.

Liquidity Drawn

Centrifuge pool draw request OR Maple loan execution → USDC/USDT disbursed to registered custodian address automatically by smart contract.

Custodian Receipt

USDC/USDT arrives at Fireblocks vault / Gnosis Safe / Anchorage address. Webhook notification triggered. Transaction hash recorded in platform audit log.

Routing Decision

Proceeds route to one of four destinations: (A) PAXG purchase via Paxos OTC → gold reserve; (B) Circle off-ramp → USD wire → CIBC Bank USA; (C) OUSG purchase via Ondo → T-bill yield; or (D) hold as USDC in custody for operating capital.

Repayment Cycle

At offering close: investor proceeds (USD) → CIBC escrow → Coinbase Prime / Circle → USDC → repay Centrifuge pool or Maple facility. Platform smart contract automates the repayment schedule.

Quick reference — what can be sent where

Q: Can Centrifuge send to a Fireblocks vault?

Yes. Register the Fireblocks-generated vault deposit address as your Centrifuge pool admin/issuer address. USDC drawdowns go there automatically.

Q: Does Maple support USDT?

Yes. syrupUSDT is an ERC-4626 token on Ethereum mainnet. Confirmed in Maple developer docs: deposit USDT, receive yield-bearing syrupUSDT, redeem to any address.

Q: Can Centrifuge proceeds go to a Gnosis Safe?

Yes. A Gnosis Safe is just an Ethereum address from the protocol's perspective. Set it as the issuer address — all drawdowns require multi-sig approval before leaving the Safe.

Q: Can Ondo OUSG be held at Anchorage?

Yes. Submit Anchorage's institutional Ethereum address to Ondo for KYC whitelist approval (standard institutional path). OUSG yield auto-accrues at that address.

Q: Is USDT available from Centrifuge?

Yes, via BSC. JTRSY and JAAA pools both have USDT vaults on Binance Smart Chain. For Ethereum, swap received USDC → USDT via Curve 3pool or Uniswap v3 (0.05% fee tier).

Q: Can proceeds be wired to CIBC Bank USA?

Yes, via Circle Business API (1:1, same day), Anchorage (OTC desk → wire), or Coinbase Prime (sell USDC → wire, same day). Circle Mint is fastest — no conversion spread.

Q: What chains does Centrifuge support?

Ethereum, Base, Arbitrum, Avalanche, Plume, BSC, Optimism, HyperEVM, Monad (smart contracts), plus Solana and Stellar (native bridge). 12 chains total per docs.

Q: Can Maple proceeds reach Solana?

Yes. Maple uses Chainlink CCIP for syrupUSDC cross-chain — Solana is a supported destination. Confirmed in Maple docs: "Crosschain (Solana, L2s and others)" integration guide.
