11 services carry this tag in their source record. Tags come from the provider, not from us — a tag is a claim about what the service does, not proof that it does it well.
🆕 The single call before trading a Base-native B20: seize (burnBlocked) + freeze (Policy Registry) + rebase + pause + uncapped-mint, collapsed into one GO/HOLD/STOP verdict with an auditable receipt. Pass wallet= to als...
🆕 b20-safety tells you WHICH powers a B20 has; this tells you WHO holds them. Reads the token's role-based access control (mint / burn / seize-via-burnBlocked / pause / admin) from onchain role events and reports the ex...
🆕 A B20 with a METADATA_ROLE holder can call updateName/updateSymbol — change its own identity after launch (an impersonation / bait-and-switch vector ERC-20 has no protocol equivalent for). Reads whether the metadata i...
🆕 Live — B20 is Base's native precompile token standard, and unlike ERC-20 a B20 issuer can freeze holders (Policy Registry) and even SEIZE your balance (burnBlocked) at the protocol level. This reads those powers — sei...
🆕 Lists the newest B20 tokens created on Base (from the B20Factory precompile) — variant, symbol, decimals, block. B20 is Base's native token standard and dozens launch hourly. A discovery feed for agents hunting new B2...
Recently deployed B20 tokens on Base: scans the factory's B20Created logs over a block window, locates each new token by its 0xB200 address prefix, and enriches it with live name/symbol/decimals eth_calls.
Payment memos attached to B20 transfers: pairs each Memo(address,bytes32) log with its Transfer at the previous log index (same tx, same token). Give a tx hash for one transaction, or scan a block window. Returns memoHex...
ERC-20 metadata plus B20 signals for any Base address: name, symbol, decimals, total supply, best-effort paused/cap, bytecode size, and whether the address carries the factory-issued 0xB200 prefix. Works on plain ERC-20s...
Boolean verdict with reasons: is this address a real factory-issued B20 on Base? Checks the 0xB200 address prefix, ERC-20 readability, and whether the B20 feature set is activated on the registry.
Is B20 live on Base mainnet? Queries the Activation Registry precompile for base.b20_asset and base.b20_stablecoin (or a custom feature id). Honest pre-launch too: reports not-activated until the registry flips.
Pure-CPU helper: turn a B20 feature string (e.g. base.b20_asset) into its bytes32 feature id and ready-to-send isActivated(bytes32) calldata for the Activation Registry. No network egress.
