post https://api.utila.io/v2/vaults//transactions/:replace
Creates a new transaction that replaces an existing signed transaction in the system which has not been mined yet.
Only works for blockchains that support replacement of signed transactions, e.g.
- Ethereum - which has nonce management.
- BTC - which has RBF (Replace-By-Fee) and CPFP (Child-Pays-For-Parent) mechanisms.
Some blockchains do not support transaction replacement, e.g. TRON - which is based on
transaction expiration time - for these cases, the transaction will be either mined or
expired after the configured expiration time.
If the transaction has not been signed yet, and you wish to cancel it, use
CancelTransaction
instead.
