syrupUSD Crosschain

syrupUSDC & syrupUSDT use Chainlink Crosschain Interoperability Protocol (CCIP) to facilitate minting, holding & redeeming on chains other than Ethereum mainnet. CCIP handles secure crosschain token movement and message delivery, so you don’t need to build a custom bridge.

Integration paths

1) Offchain integrators (bridge, wallets & aggregator UIs)

If you run a bridge, wallet, or aggregator UI, use the token and router addresses per chain (below) to configure your routes and call patterns. Typically, you won’t deploy onchain contracts - your UI directs users to call the CCIP Router with the correct params.

2) Onchain integrators (protocols)

If your protocol needs to bake in crosschain syrupUSDC transfers, implement CCIP send/receive flows in your smart contracts and interact with the Router on the source chain, please contact us at [email protected].

syrupUSDC Testnet: networks & addresses

CCIP provides two ERC-20 test tokens, so you don’t depend on third-party liquidity while testing:

• CCIP-BnM (Burn & Mint): deployed on each testnet; transfers are burn → mint

• CCIP-LnM (Lock & Mint): minted only on Ethereum Sepolia

High-level flow

1. User picks source & destination chains in your UI or protocol flow

2. Approve syrupUSDC / syrupUSDT to the CCIP Router on the source chain (standard ERC-20 approval; Solana uses SPL program approvals)

3. Initiate CCIP transfer via the Router with destination chain selector, recipient, and amount

4. CCIP finalizes on destination chain and releases/mints syrupUSDC / syrupUSDT to the recipient

Implementation notes

• Always call the Router listed for the source chain; don’t hit low-level endpoints directly

• Chain selectors & fees: Pull chain selectors and fee token options from the CCIP directory; keep them in config

• Solana (SVM) specifics: Use the SVM Router program (ccip_send) and follow the SVM API docs for building send/receive flows

• Observability: Track the CCIP message ID from the Router response and correlate with destination events

• If you require market data streams or feeds, please see Data Streams & Oracles
