⚡Blockchains
We support all major public blockchains
expand.network provides connectivity to various EVM and Non-EVM based chains for both, query(Read) and transaction(Write). So now, the developer does not need to worry about how different blockchains work. The developer will be required to know only the chainID to perform multiple operations on different chains.
For example, if a developer wants to send two transactions, one on the Ethereum mainnet and another on Solana, then they just need to call the sendtransaction API with different chain IDs in the request body.
Following are the common APIs implemented for all the various chains:-
Name | Type | Description |
---|---|---|
getbalance | Read | Get the balance or number of the given token in the requested public address. |
getblock | Read | Get details of a block. |
getgasprice | Read | Get the current gas price from the network. |
getstorage | Read | Get data stored in the given slot. |
gettransaction | Read | Get details of a transaction. |
Read | Get the RPC of required chain. | |
getgasfees | Read | Retrieves gas fee spent in a particular range. |
getusertransactions | Read | Get the historical transaction details for a specific user address. Available on Ethereum, Binance Smart Chain, Avalanche - P/C/X, Polygon, Fantom, Stellar and TON. |
gethistoricalrewards | Read | Get the historical transaction details focusing on staking rewards for a specific user address. Available on Avax-P. |
getevents | Read | Get a filtered list of events emitted by a given ledger range, within a maximum 24 hours of recent ledgers. Currently available on Stellar. |
getlatestledger | Read | Get details for the current latest known ledger of the node. Currently available on Stellar. |
portfolio | Read | Get detailed information about the verified assets or tokens currently associated with a user's wallet address. Available on Ethereum as well as Arbitrum, Avalanche, Base, Binance Smart Chain, Cronos, Fantom, Near, Optimism, Polygon, Stellar and Solana. |
getflashbotblocks | Read | Get details of the flashbot blocks. |
getflashbottransactions | Read | Get details of the flashbot transactions. |
getflashbotbundle | Read | Get details of the specified flashbot bundle. |
gettokenmarketdata | Read | Get the market data for a given asset on the Ethereum chain. |
gettokenmapping | Read | Get the top 40 popular tokens on the EVM chains |
getapprovaldata | Read | Retrieves approval-related information for a specified address, including token details, amount approved, spender, risk factor, value at risk, and timestamp. Currently supported for Ethereum chain. |
Write | This endpoint lets users collect fees on transactions via the Expand API or plug-in. | |
estimategas | Write | Generates and returns an estimate of how much gas would be necessary to complete a transaction. |
settrustline | Write | Implement a trustline between issuer and distributor. Currently available on Stellar. |
rwa/issue | Write | Executes a payment operation to create (or mint) an asset on the Stellar network. |
rwa/freeze | Write | Executes a transaction to revoke an existing trustline’s authorization, thereby freezing the asset held by an account on the Stellar network. |
rwa/burn | Write | Executes a transaction to burn or delete an asset on the Stellar network. |
rwa/transfer | Write | Trigger a payment operation to send an amount in a specific asset (XLM or non-XLM) to a destination account on the Stellar network. |
sendtransaction | Write | Sign and send transactions on the chain. |
createaccount | write | Initiates a transaction to fund a newly created account using the public key as the account ID. |
simulatetransaction | write | Submit a trial contract invocation to simulate how it would be executed by the network. This endpoint calculates the effective transaction data, required authorizations, and minimal resource fee. It provides a way to test and analyze the potential outcomes of a transaction without actually submitting it to the Stellar network. |
genericsmartcontractmethod | Write | Calls read functions of verified smart contracts. Available on ethereum. |
decodetransaction | Write | Get the decoded transaction for the provided raw transaction. Available on ethereum, binance, avalanche, polygon, cronos, arbitrum, fantom, optimism, solana, stellar and near. |
Read | Retrieves approval-related information for a specified address, including token details, amount approved, spender, risk factor, value at risk, and timestamp. This is currently available for EVM chains |
Every chain requires a different set of parameters to perform the common operations. Please refer to the sub-sections for details.
To perform sendtransaction() successfully, the user needs to sign the transaction first.

If the user wants to pass the RPC manually, the user can either use their own RPC or use our provided RPC, by using /getpublicrpc endpoint.
/getpublicrpc
Get the RPC of required chain.
