SeaDrop Is Now Open Source

SeaDrop, a registry used by OpenSea to launch NFT drops, is now Open Source. SeaDrop streamlines the minting process for NFT drops on EVM blockchains. Creators can build their token drop in a single interface. The contract supports public drops, allow list stages, token gated drops, and server-side signed mints.

The SeaDrop repo also includes support for ERC-721A, a gas-optimized extension of ERC-721. The open-source release allows anyone to build a token that integrates into SeaDrop's standardized mint logic. A future release of the smart contract standard will include support for reverse dutch auctions and ERC20 token payments.

Lens Protocol Implements ENS Resolution

Lens Protocol data can now be queried via ENS off-chain resolution. The protocol is using EIP-3668, aka CCIP Read, to enable secure offchain data retrieval. The implementation allows contracts to request Lens data asynchronously. Since Lens Protocol is based on Polygon, it is unable to implement on-chain resolution with ENS.

Lens Protocol currently operates a resolver for its DNS domain. It plans to open-source its resolver to allow anyone to create their own off-chain resolver serving Lens data. A dedicated resolver is used to fetch information from an off-chain source and formats data to be understood by the client.

Ribbon Lend Now Live

Ribbon Lend, a credit market that gives institutions access to unsecured loans, is now live. The credit market allows users to deposit assets into unsecured lending pools to receive upwards of 10% APY. Algorithmic market maker Wintermute and crypto trading firm Folkvang are the first two institutional borrowers on the platform.

The institutions have been evaluated for creditworthiness by private credit oracle Credora. Ribbon Lend currently holds $9.3 million USDC in user deposits so far, earning users 7% APY. According to Ribbon, Lenders can exit their position at any time as long as the pool has liquidity.
