RSK Network


RSK is the first general purpose smart contract platform secured by the Bitcoin Network. RSK’s Contracts goal is to add value and functionality to the bitcoin Contracts ecosystem by enabling smart contracts, near instant Contracts payments, and higher scalabiity. RSK Blockchain is connected to Bitcoin through Merged Contracts Mining and a two-way peg also known as the bridge.

The RSK blockchain is highly decentralised. RSK is merge-mined with Bitcoin, and has a hashpower that is second only to Bitcoin. As such, it is believed to be the most secure and censorship resistant smart contract platform. Refer to RSK Stats for the live value of the RSK hash rate.

Supported endpoints

Get token balances for address
Class A
Given chain_id and wallet address, return current token balances along with their spot prices. This endpoint supports a variety of token standards like ERC20, ERC721 and ERC1155. As a special case, network native tokens like ETH on Ethereum are also returned even though it’s not a token contract.
GET /v1/:chain_id/address/:address/balances_v2/
Get transactions for address
Class A
Given chain_id and wallet address, return all transactions along with their decoded log events. This endpoint does a deep-crawl of the blockchain to retrieve all kinds of transactions that references the address including indexed topics within the event logs.
GET /v1/:chain_id/address/:address/transactions_v2/
Get ERC20 token transfers for address
Class A
Given chain_id, wallet address and contract-address, return all ERC20 token contract transfers along with their historical prices at the time of their transfer.
GET /v1/:chain_id/address/:address/transfers_v2/
Get token holders as of any block height
Class A
Given chain_id and wallet address, return a paginated list of token holders. If block-height is omitted, the latest block is used.
GET /v1/:chain_id/tokens/:address/token_holders/
Get log events by contract address
Class A
Given chain_id and contract address, return a paginated list of decoded log events emitted by a particular smart contract.
GET /v1/:chain_id/events/address/:address/
Get log events by topic hash(es)
Class A
Given chain_id and topic hash(es), return a paginated list of decoded log events with one or more topic hashes separated by a comma.
GET /v1/:chain_id/events/topics/:topic/
