Token Standards

SRC-20

Fungible token standard, like ERC-20. Anyone can deploy.

sentrix token deploy --name "My Token" --symbol "MTK" --supply 1000000 --decimals 18 --deployer-key <key> --fee 100000

Creates contract at SRC20_<sha256(txid)>. Full supply minted to deployer. Fee: 50% burn, 50% ecosystem.

Transfer: sentrix token transfer --contract SRC20_... --to 0x... --amount 1000 --from-key <key> --gas 10000

Burn: sentrix token burn --contract SRC20_... --amount 500 --from-key <key> --gas 10000

Approve: Allow a third party to spend your tokens. Must reset to 0 before setting a new allowance (prevents the classic ERC-20 front-running attack).

Mint: Owner only. Can't exceed max_supply set at deploy.

All operations need SRX for gas — you need SRX even if you're only moving tokens.

Endpoint	Method
`/tokens`	GET — list all tokens
`/tokens/{contract}`	GET — token details
`/tokens/{contract}/balance/{addr}`	GET — balance
`/tokens/deploy`	POST — deploy (needs API key)
`/tokens/{contract}/transfer`	POST — transfer (needs API key)
`/tokens/{contract}/burn`	POST — burn (needs API key)

Explorer: /explorer/tokens and /explorer/token/{contract}.

	ERC-20	SRC-20
Gas token	ETH	SRX
Contract address	EVM deployment	`SRC20_` + deterministic hash
Approve front-run	Vulnerable	Mitigated (reset to 0 first)
Max supply	Optional	Built-in, enforced in mint()
VM	EVM	Native engine (Pioneer), revm (Voyager)

First native SRC-20 token on Sentrix (deployed via the Pioneer-era native SRC-20 engine, not the EVM). Sentrix Utility.

Planned uses: governance, fee discounts, staking boosts.

SRC-20 (Voyager): EVM-compatible via revm. Solidity ABI, gas metering, events.

SRTX (Future): USD-pegged stablecoin. SRX-collateralized.
