stellar-suite

stellar-suite is a JS library to handle stellar easily and usefully. It wraps js-stellar-sdk within. Payment and multisig transactions tend to be complicated JS code, but you can implement them easily by using stellar-suite. MemoText can be added to a transaction, but the limit 28-byte . This limit is cleared by working with Ethereum SWAM.

How to install

npm install stellar-suite
