token
Создание и управление взаимозаменяемыми токенами на Convex. Используйте, когда пользователь хочет создать новый токен, проверить балансы токенов или управлять эмиссией токенов.

Fungible tokens use the @convex.fungible standard library
(convex-core/src/main/cvx/convex/asset/fungible.cvx). See the convex-lisp
skill for CVM conventions, and transact for how transactions are signed.
Create a New Token
Fixed supply — no further tokens can ever be minted:
(deploy (@convex.fungible/build-token {:supply 1000000}))
Mintable — build-token alone provides no mint or burn capability. To
allow minting you must compose add-mint into the same deployment:
(deploy [(@convex.fungible/build-token {:supply 1000000})
(@convex.fungible/add-mint {:minter *address* :max-supply 1000000000})])
Decide which the user wants before deploying — the choice is permanent, and a
token deployed without add-mint fails on any later mint attempt.
build-token config: :supply (defaults to 0), :initial-holder (defaults to
*address*), :decimals. add-mint config: :minter (any trust monitor,
defaults to *address*) and :max-supply (from protocol v1, defaults to
unlimited).
Always set :max-supply explicitly. Before v1 activates, omitting it
defaults the cap to 0 — and because 0 is truthy in CVM, that installs a
zero cap which blocks all minting, silently producing a mintable-looking
token that can never mint (#528). Setting it explicitly is correct under both
genesis and v1. See the protocol-versions skill.
deploy returns the token's actor address.
Operations
| Task | Source |
|---|---|
| Check balance | (@convex.fungible/balance #TOKEN #HOLDER) |
| Total supply | (@convex.fungible/total-supply #TOKEN) |
| Decimals | (@convex.fungible/decimals #TOKEN) |
| Transfer | (@convex.fungible/transfer #TOKEN #DEST AMOUNT) |
| Mint | (@convex.fungible/mint #TOKEN AMOUNT) |
| Burn | (@convex.fungible/burn #TOKEN AMOUNT) |
There is no quantity function — it returns :UNDECLARED. Total supply is
total-supply.
balance, total-supply and decimals are reads: use a query, not a
transaction. transfer, mint and burn change state and must be
transactions.
If a Convex MCP server is configured, its getBalance and transfer tools
also accept a token parameter.
Authorisation
Minting requires the caller to satisfy the token's :minter trust monitor;
anything else fails with :TRUST. :minter takes any trust monitor, not just
an address — see the trust skill for composing them (a mint window, a
multi-party whitelist, delegated revocation). Creating, transferring, minting and burning
are all transactions, so they need a key the user has supplied — see the
transact skill. Without one you can prepare the source but not execute it.
