GHO (GHO)

Very interesting. @Aave is taking sGHO cross-chain, and it's leveraging @chainlink's CRE for it.

A new ARFC extends the same Chainlink CCIP rail that GHO runs on, now to sGHO.

Essentially, a single ERC-4626 vault stays on Ethereum as the source of truth, and the sGHO token gets distributed across L2s. This is the same model @LidoFinance uses for wstETH.

The new implementation is the dual-lane design: Fast Lane and Standard Lane.

> Fast lane: pre-funded sGHO and GHO sit on the L2, so retail-sized deposits swap GHO <> sGHO instantly at vault rate. A Chainlink CRE workflow sweeps the GHO back to mainnet, mints, and bridges sGHO back to refill.

> Standard lane: larger deposits route to the mainnet vault directly. ~40 min round trip on CCIP v1, dropping toward ~5 min once v2's faster finality is live.

In both cases, fees are paid in GHO. So, no extra gas token needed.

The initial Arbitrum launch will be provisioned with $1.2M in local liquidity, and Trail of Bits (the original auditor of Chainlink's wstETH

Cross-chain GHO bringing predictable 4.25% savings rates across multiple networks.
