SPL tokens

Set up#

Install the SPL Token CLI (cargo install spl-token-cli) and create a test-only keypair. Fund its address from the faucet(opens in a new tab) — fees are paid in KYV. Every command below passes Kyvro's RPC explicitly with --url.

export KYVRO_RPC=https://rpc-testnet.kyvro.si
solana-keygen new --outfile ~/.config/solana/kyvro-test.json
solana address --keypair ~/.config/solana/kyvro-test.json   # fund this address from the faucet

These are the same addresses as on Solana, preloaded at genesis and immutable. Token-2022 commands select that program explicitly (see spl-token --help); the default is SPL Token.

Create a mint#

spl-token create-token --url $KYVRO_RPC
# Creating token <MINT>
spl-token supply <MINT> --url $KYVRO_RPC   # 0 to start

The mint defines the token: decimals, mint authority and freeze authority. Keep the mint address — it is the token's only stable identifier. For reference, the faucet's tKUSD mint is FPwMXWSGLm8ZBi5YDJroGMZjXqnYQgCmGCzVqs3YcgXe.

Token accounts#

Tokens live in Associated Token Accounts (ATAs), one per owner per mint — see how ATAs work. Create yours before minting:

spl-token create-account <MINT> --url $KYVRO_RPC
spl-token accounts --url $KYVRO_RPC

Mint and transfer#

spl-token mint <MINT> 1000 --url $KYVRO_RPC
spl-token transfer <MINT> 10 <RECIPIENT_ADDRESS> --url $KYVRO_RPC
spl-token balance <MINT> --url $KYVRO_RPC

Inspect on the explorer#

Paste the mint into the explorer(opens in a new tab): the token page shows decimals, supply, mint and freeze authorities, and the largest holders. Try it with tKUSD at the tKUSD page(opens in a new tab).
