Etherspot NPM | npm.io

Etherspot SDK

Etherspot is a blockchain development framework for EVM-compatible chains that creates direct state channel bridges to provide a seamless user experience across chains and wallets.

With just one deposit you’re able to onboard your users to the entire multichain world.

Developers can use the Buidler and TransactionKit tools to easily include Etherspot features into their dapps.

For more powerful but complex uses, developers can dive deeper into the SDK and explore a number of custom use cases.
