On-chain Interactions

use these operations for arbitrary contract execution and chain level protocol actions such as staking and resource delegation these transactions can have chain specific data requirements and may require approval before broadcast create a contract call post /api/external/transactions/ rest request body { "vaultid" "vault 123", "blockchain" "ethereum", "amount" "0", "category" "contract call", "data" { "calldata" "0xa9059cbb000000000000000000000000 ", "toaddress" "0xtokencontract1234567890abcdef" }, "externalid" "contract call 1001", "gasparams" { "feetier" "medium" }, "creationoptions" { "skippreprocesssimulation" false } } response { "id" "transaction contract 123", "orgid" "org 456", "vaultid" "vault 123", "status" "pending", "transactiontype" "outgoing", "category" "contract call", "subcategory" "contract call", "createdat" "2026 08 04t11 00 00z", "updatedat" "2026 08 04t11 00 00z", "isdeleted" false, "externalid" "contract call 1001", "source" { "type" "vault", "id" "vault 123", "name" "treasury vault" }, "blockchain" "ethereum", "amount" "0" } javascript sdk interface createcontractcalltransactionrequest { vaultid string; chain string; amount? string; data? \| { calldata string; toaddress? string } \| { canisterid string; method string; arg string } \| { messagehex string } \| { method string; params record\<string, unknown> }; externalid? string; gasparams? { feetier?
