Wallets are ideal for solutions requiring access to deposit addresses that do not expire, can accept an unlimited amount of deposits, and provide instant deposit webhook notifications. Due to the custodial nature of wallets (custodied by CoinStack), the private keys are always safe.
Benefits of using CoinStack's Wallet APIs include fee-less consolidation of funds, which is particularly useful when dealing with Ethereum based tokens such as USDT, where consolidation costs can reach in excess of $5 per deposit. Without CoinStack's Wallet APIs, every USDT wallet that receives a deposit would need to be funded with ETH to cover the transaction fee when transferring the USDT to a master wallet.
CoinStack automatically takes care of the consolidation process, does not charge any fees for funding addresses with ETH, and instantly credits your account before funds have been consolidated.
