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	Model	Integration	Details
	Apyx apxUSD	direct	Bridged	Chainlink CCIP (LockReleaseTokenPool)	TokenAdminRegistry maps apxUSD to pool `0x0e9c…5BB5` (LockReleaseTokenPool 1.6.1) — canonical apxUSD is escrowed on Ethereum; Base holds a bridged representation
	Centrifuge JAAA	direct	Mints native	Chainlink CCIP (2-of-2 MultiAdapter)	Second half of the 2-of-2 quorum with LayerZero V2; a forged message reaching the Spoke could mint JAAA, but BOTH bridges must be compromised
	Maple (syrupUSDC)	direct	Bridged	Chainlink CCIP (LockReleaseTokenPool)	LockReleaseTokenPool holds ~13% of supply on mainnet, backing bridged syrupUSDC on Base/Arbitrum/Solana

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

	Protocol / Token	Type	Model	Integration	Details
	Across Protocol	direct	Transport	LayerZero OFT (asset routes)	The assessed asset is the V2 LP token, which is not bridged; Across integrates LZ OFT to move bridged assets through its own routes
	Centrifuge JAAA	direct	Mints native	LayerZero V2 (2-of-2 MultiAdapter)	Spoke `0xEC35…25aB` holds `wards` mint authority on JAAA and mints on cross-chain message; 5 DVNs on the LZ side and a 2-of-2 quorum with CCIP mean BOTH bridges must be compromised
	Midas mHYPER	direct	Mints native	LayerZero OFT Adapter (MidasLzMintBurnOFTAdapter)	Adapter holds M_HYPER_MINT_OPERATOR_ROLE (mint has no onchain backing check) and the burn role
	Paxos USDG	direct	Mints native	LayerZero V2 OFT (OFTWrapper)	OFTWrapper is Supply Controller SC3 with 45M USDG mint capacity (~521 USDG/sec refill) — the bridge can mint native USDG
	Re (reUSD)	direct	Mints native	LayerZero OFT (ReMintBurnAdapter)	ReMintBurnAdapter holds a live cross-chain mint path on reUSD; active on Avalanche, Arbitrum, Base, BNB; 2.5M/24h rate limit
	Resolv RLP	direct	Bridged	LayerZero OFT Adapter	OFT Adapter `0x234c…d06c` escrows canonical RLP on Ethereum (133,516 RLP locked of 14.64M supply); remotes are bridged OFTs
	Resolv wstUSR	direct	Bridged	LayerZero OFT Adapter	OFT Adapter `0xab17…1978` escrows canonical wstUSR (406,723 locked, ~22% of supply); live on Arbitrum, Base, BSC, Bera, Soneium, HyperEVM, TAC
	Sky USDS	direct	Bridged	LayerZero V2 OFT Adapter	Adapter locks USDS for Solana + Avalanche (~48.7M locked) and does NOT hold `wards` on USDS — it cannot mint native USDS
	Fluid	indirect	Bridged	rsETH market exposure	Inherits rsETH's LayerZero OFT Adapter model (canonical rsETH escrowed on Ethereum)
	KernelDAO hgETH	indirect	Bridged	Wraps rsETH (Kelp DAO)	rsETH bridges via OFT Adapter `0x85d4…8Ef3`, which escrows 46,254 rsETH (~9.6% of supply) — it cannot mint native rsETH
