transact
Ejecuta una transacción CVM en la red Convex. Úsalo cuando el usuario quiera modificar el estado en cadena, llamar funciones de actor o definir valores.

Transactions modify global state atomically. They consume juice, paid in copper by the origin account, and must be signed.

Authorisation
A transaction requires a key. You have one only if the user has supplied it — a signing-service passphrase, or a raw seed. There is no ambient authority here, so:
- User has a key in the signing service — use the MCP
signingTransacttool with their address and passphrase. - User has a raw seed — use the MCP
transacttool with address and seed. - Neither — you cannot execute. Use
prepareto build the unsigned transaction, or the CLI below, and hand it back for the user to sign.
Do not treat case 3 as a blocker to work around. Preparing the transaction and returning it is the correct outcome.
Via the CLI
Works from a built convex.jar and needs no MCP server:
java -jar convex.jar client transact -a #13 '(def my-var 42)'
java -jar convex.jar client transact -a #13 -k <key> -p <keypass> '(transfer #42 1000000000)'
-k / --key selects the key from the keystore and -p / --keypass is its
passphrase; --keystore and --storepass select the keystore itself. Add
--host / --port for a non-default network.
Common Patterns
| Task | Source |
|---|---|
| Transfer coins | (transfer #DEST AMOUNT) |
| Define a value | (def my-var 42) |
| Call an actor | (call #ACTOR (function-name arg1 arg2)) |
| Call a library | (@convex.fungible/transfer #TOKEN #DEST AMOUNT) |
| Set controller | (set-controller #ADDR) |
Confirm source, destination and amount with the user before executing anything that moves value or changes account control. State what will happen in CVM units, not copper.
