7/ Since WAIaaS focuses purely on wallet security, it integrates easily with existing agent projects. REST API, TypeScript SDK, and MCP server — just replace direct signing with a WAIaaS API call. Your agent logic stays the same, your wallet security levels up.

1/ You're giving your AI agent the entire wallet key?

Conway/Automaton, ElizaOS, Virtuals Protocol, Solana Agent Kit — AI agents transacting autonomously on-chain is growing fast.

But most share a dangerous design: the agent has direct access to the private key.

6/ Prompt Guard protects the front door. WAIaaS structurally isolates the wallet itself. Even if prompt defense is bypassed, the key is unreachable.

WAIaaS is designed with the assumption that the agent WILL be compromised.

[Minho Yoo | WalletGuy @WalletGuyYoo]

@0xSigil @ConwayResearch Conway + WAIaaS could be a natural fit:

— Both MCP-native
— Both support x402
— Both target EVM + Solana
— Daemon runs on the same VM Automaton already provisions

One process added. Zero autonomy lost. Four of @VitalikButerin's risks addressed.

The Web4 thesis is right: AI agents should earn, own, and transact autonomously.

But there's a design flaw in how agent wallets work today — the agent holds the private key directly.

Compromised agent = drained wallet. Every time.

Here's a better way 🧵

[Minho Yoo | WalletGuy @WalletGuyYoo]

Autonomy ≠ key access. These are two separable concerns.

An agent can transact autonomously WITHOUT holding the private key.

WAIaaS separates them:
— Agent gets a scoped session token
— Daemon holds the key
— Policy engine sits between

Same autonomy. Structurally safer.

Agent compromised? Damage bounded by policy, not unlimited.
