Query UTxOs

UTxOs (Unspent Transaction Outputs) represent available funds on the blockchain. Evolution SDK provides several methods to query UTxOs based on different criteria.

By Address

import { ,  } from "@evolution-sdk/evolution"

const  = ({
  : "preprod",
  : { : "blockfrost", : "https://cardano-preprod.blockfrost.io/api/v0", : ..! },
  : { : "seed", : ..!, : 0 }
})

const  = .("addr_test1vrm9x2dgvdau8vckj4duc89m638t8djmluqw5pdrFollw8qd9k63")
const  = await .()

for (const  of ) {
  .("UTxO:", ., "#", .)
  .("  Lovelace:", ..)
}

Wallet UTxOs

Query all UTxOs belonging to your connected wallet:

import {  } from "@evolution-sdk/evolution"

const  = ({
  : "preprod",
  : { : "blockfrost", : "https://cardano-preprod.blockfrost.io/api/v0", : ..! },
  : { : "seed", : ..!, : 0 }
})

const  = await .()
const  = .((, ) =>  + .., 0n)
.("Total balance:", , "lovelace")

By Asset

Find UTxOs containing a specific native token:

import { ,  } from "@evolution-sdk/evolution"

const  = ({
  : "preprod",
  : { : "blockfrost", : "https://cardano-preprod.blockfrost.io/api/v0", : ..! },
  : { : "seed", : ..!, : 0 }
})

const  = .("addr_test1vrm9x2dgvdau8vckj4duc89m638t8djmluqw5pdrFollw8qd9k63")
const  = "7edb7a2d9fbc4d2a68e4c9e9d3d7a5c8f2d1e9f8a7b6c5d4e3f2a1b0c9d8e7f6"

// UTxOs at address containing this token
const  = await .(, )

// Find the single UTxO holding an NFT (unique token)
const  = await .()

By Output Reference

Fetch specific UTxOs by their transaction hash and output index:

import {  } from "@evolution-sdk/evolution"

const  = ({
  : "preprod",
  : { : "blockfrost", : "https://cardano-preprod.blockfrost.io/api/v0", : ..! },
  : { : "seed", : ..!, : 0 }
})

declare const : any[]

const  = await .()
