Summary

  • Babylon Labs submitted a Temp Check proposal in May 2026 to integrate native Bitcoin collateral into Aave V4 through Trustless Bitcoin Vaults.
  • Aave V4 introduces modular architecture to support GHO stablecoin growth alongside a $50M buyback program.
  • GHO continues cross-chain expansion to networks including Arbitrum and Base.

Babylon Labs pitched a Temp Check to the Aave DAO in May 2026. They aim to bring native Bitcoin collateral straight into Aave V4. Trustless Bitcoin Vaults form the core idea. Users could borrow against plain BTC without wrapped bridges or extra tokens.

This targets growing demand for decentralized stablecoins and real Bitcoin lending.

The plan stays early. Full DAO approval must come first.

Context

Aave created GHO as its native overcollateralized stablecoin. The team launched it on Ethereum first. Expansion to other chains followed.

Aave V4 uses a modular design. This setup should help GHO scale and support fresh features.

Babylon Labs builds Bitcoin staking tools. Their proposal matches efforts to pull raw BTC into lending markets. Wrapped BTC still dominates volumes.

Details

The Temp Check highlights Trustless Bitcoin Vaults as the key piece. Users deposit native BTC directly. The vaults manage collateral for borrowing inside Aave V4.

This setup skips wrapped BTC risks. Aave V4 keeps lending logic separate from new collateral types. The upgrade also adds a $50M buyback program for GHO. GHO stays fully backed and clear. Rollouts to Arbitrum and Base happened in early 2026.

The outcome hinges on the Aave DAO vote. Approval would push the vaults into testing on Aave V4. Further checks on GHO metrics and collateral flows would follow.
