Usage

import cst from '@cryptoseller-tools/payments-sdk-v1';

async function approveAndTransfer(){
    const provider = new ethers.BrowserProvider(window.ethereum); // or any other Eip1193Provider
    const signer = await provider.getSigner()

    const recipientId='0x0123...' // bytes32 in solidity
    const token='0x123...' // token address
    const id='0x123...' // bytes32
    const payload = JSON.stringify({
            name:'CST.Pay example',
            desc:'Test payload object'
        })
    const amount='100.2005' // real number, will be converted to 'wei' based on selected token's decimals.

    const a = await cst.approve({ token, amount, signer, wait: true });

    if(a.status){
        const t = await cst.transfer({ recipientId, amount, token, payload, id, signer, wait: true });
        return t.status? t.payload : t.error
    }else{
        return a.error
    }
