It existed for quite a while now as an internal tool used by us to manage fleet of wallets for us and our customers, starting as a simple abstraction layer on top of common client libraries and later we started using our custom developed modules for transactions compilation and broadcasting. We are certainly not the first in this niche, but what made us turn this into a separate service is how inconsistent and unnecessarily complex other services looked to us. If you wanted to support several networks you would have to use different providers for this, and their user experience was far from convenient.
As of now it’s still very young service and only supports primitive operations like creating transactions with chain-native coins, ERC/TRC tokens, UTXO picking and multi output transactions for Bitcoin, fees and gas prices fine tuning. Despite that we have many more features nearing launch: Support for any custom ERC/TRC tokens, Tron bandwidth and energy staking management, batched transactions and many more.
We can’t wait to hear your feedback, suggestions and requests on more features. Our website: https://1151.to
