Bridge Dependencies

Chainlink's cross-chain interoperability protocol. Messages are validated by the Chainlink DON with a Risk Management Network; tokens move via burn/mint or lock/mint token pools.

	Protocol / Token	Type	Integration	Details
	Apyx apxUSD	direct	Chainlink CCIP	Uses CCIP for cross-chain transfers (no LayerZero dependency)
	Centrifuge JAAA	direct	Chainlink CCIP (2-of-2 MultiAdapter)	Second half of the 2-of-2 quorum alongside LayerZero V2
	InfiniFi	direct	Chainlink CCIP + LayerZero	Cross-chain support added in PR 224
	Maple (syrupUSDC)	direct	Chainlink CCIP (LockReleaseTokenPool)

Circle's Cross-Chain Transfer Protocol moves native USDC by burning on the source chain and minting on the destination, gated by Circle's off-chain attestation service. Using canonical CCTP removes third-party lock-and-mint bridge risk; the trust assumption reduces to Circle's availability and attestation finality.

	Protocol / Token	Type	Integration	Details
	Gauntlet gtUSDa	direct	Circle CCTP V2 (native burn/mint)	Bridges USDC across Base/Arbitrum/Optimism to Morpho
	Origin OUSD	direct	Circle CCTP V2	Cross-chain strategies bridge ~42% of TVL to Base and HyperEVM
	Yearn yvUSD	direct	Circle CCTP V2 (CCTPStrategy)	Bridges USDC to Arbitrum (funded, ~3.5%) and Base (added, 0 debt); Katana uses AggLayer separately
	Flex	indirect	Collateral is yvUSD (which bridges via CCTP)

Generic cross-chain messaging. Tokens bridge via the OFT / OFT-Adapter standard; security depends on the configured DVN (Decentralized Verifier Network) set and the token's mint/burn authority on each chain.
