ReNFT - A leading multi-chain NFT rental protocol.
Install
yarn add @renft/sdk
Usage
Our SDK comes in two flavors. One tuned to use with ethers and one tuned to use with viem.
The below is a simple example of lending an ERC721, note that the amount is ignored, you will always lend 1 unit of ERC721 token.
If you are having any issues with the below code, go here and ensure your dependencies for ethersproject are the same as ours (in package.json).
You might be wondering what 'AZRAEL' refers to in the below import. If so, go to our docs here. Azrael, Sylvester and Whoopi are our naming conventions to refer to different flavors of our contracts.

Deploying New SDK versions
Make sure the
CHANGELOG.mdis updated accordingly!
Create a utility shell scripts for deploys locally like the one below:
#!/bin/bash
set -e
yarn build
yarn publishmake sure to make it executable:
chmod +x deploy.sh
