Overview

"AWS for public blockchain transactions"

The Managed Transactions API enables traditional enterprise procurement of public blockchain services without the need to ever buy or hold cryptocurrency.

Users are billed in arrears based on transaction volume. Fees incurred when using the Managed Transactions API are billed in arrears and always expressed in terms of the customer's choice of fiat currency.

Supported Methods

The Managed Transactions API supports the following methods of operation:

Method	Use-Case
Broadcast	the API signs arbitrary calldata and broadcasts a transaction to a named recipient
Subsidize	the API sends exact funds needed to execute the contemplated transaction to a named beneficiary, which broadcasts the transaction upon receipt of the subsidy

Supported Networks

The Managed Transactions API could theoretically support any public blockchain. The following networks are currently supported:

Network	Currencies	Supported Methods	Base Cost	Pricing
Ethereum	ETH	Broadcast, Subsidize	gas¹	Contact Us
Polygon	MATIC	Broadcast	gas¹	Contact Us

¹ Value transfers (i.e., payment of cryptocurrency or tokens to a third party) are not currently supported by the Managed Transactions API. Such transfers may be supported in a future release. As of today, this service only pays the fee to broadcast transactions to the network (i.e., gas).
