Grace Protocol

Protocol-neutral payment rail for AI agents. Ship agents that pay for things. @x402 and @mpp behind one unified interface, settled on @solana.

$GRACE is live on @solana!

The utility token for Grace Protocol. Holders can pay for managed infrastructure with $GRACE and get 10% off vs. USDC.

Grace Protocol is the unified payment layer for AI agents. One API that speaks both @x402 and @mpp, settles every transaction on Solana, and gives every agent a wallet with built-in spend controls.

Grace Protocol docs are live on our website.

🔗 Docs: https://t.co/aldxYEMO1s

Clean rails for autonomous AI payments:
x402 + MPP routing, non-custodial agent wallets, spend policies, and Solana settlement.

No messy payment logic.
No protocol fragmentation.
One payment layer for agents.

Start with the docs. Build from there.

[Grace Protocol @GraceProtocolHQ]

The Grace Protocol flow in detail:

1. Agent calls endpoint
2. Server returns 402 with payment requirements
3. Gateway parses headers, identifies x402 or MPP
4. Wallet signs payment instruction
5. Transaction submitted, hash returned in response
6. Original request replayed with proof

All inside one request.

[Grace Protocol @GraceProtocolHQ]

One call. Any protocol.

https://t.co/adGBSfxx8i() detects x402 or MPP at the gateway, signs the payment, settles on Solana, and hands you back the response with a transaction hash attached.

One integration. No protocol code.

Only with Grace Protocol.

We have shipped 6 upgrades to the Grace Protocol Solana program today:

🧾 Weekly spend budgets alongside daily caps
🧊 Protocol-level emergency freeze (admin can halt an agent without touching funds)
🏦 withdraw_funds: owners always reclaim USDC, even when frozen
🔑 transfer_ownership for KMS key rotation without redeployment
🐞 Bug fix: rate-limit counter was silently consumed by low-value payments
🕐 Full event trail: freeze/unfreeze, withdrawals, ownership transfers
👥 Non-custodial throughout: freeze blocks payments, never withdrawals.

[Grace Protocol @GraceProtocolHQ]

Grace Protocol is turning agent payments into actual infrastructure.

One API for x402 + MPP.
Native Solana settlement.
Wallet controls built for autonomous agents.

Not another payment wrapper.
The payment layer for every protocol.

[Grace Protocol @GraceProtocolHQ]

Just the beginning of more to come.

$GRACE

[HelmutPay @HelmutPay]

$HELMUTPAY users will soon be able to transact on MPP!

This is in addition to the x402 protocol that we already provided access to.

Powered by using the unified interface across both protocols from @GraceProtocolHQ.

[Grace Protocol @GraceProtocolHQ]

Every Grace Protocol payment is an on-chain record any other Solana program can read.

Build invoicing on top. Build agent reputation on top. Build agent escrow on top.

The ledger is public and the primitives are open.

[Grace Protocol @GraceProtocolHQ]

Grace Protocol is the payment interface for AI agents.

→ One unified interface for x402 and MPP
→ Solana settlement, on-chain by default
→ Agent wallets and spend policies built in
→ No percentage take, no custody, no lock-in

GM from $GRACE!

Time to start building.

[Grace Protocol @GraceProtocolHQ]

Agents will move trillions before this decade is over.

The interface powering them should be public, neutral, and fast.

That's what Grace Protocol is.

$GRACE

[Grace Protocol @GraceProtocolHQ]

For all the real builders out there.

The whole point of Grace Protocol is that you don't have to choose between x402 and MPP, or rewrite payment logic for either.

If that's a problem you're hitting, our DMs are open. We'll get you integrated.

[HelmutPay @HelmutPay]

@GraceProtocolHQ Amazing perception, the birth of x402 and MPP definitely caused a HUGE splinter and time drain for us at HelmutPay.

Will be interesting to see what Grace Protocol can solve for us.

[Grace Protocol @GraceProtocolHQ]

Hong Kong, three weeks ago.

Our conversation was about agents: how many were already in the wild, how much money they were already moving, and how the rails underneath them were splintering into protocol silos before the category even had a name.

x402 was settling tens of millions of transactions on Solana. MPP had just landed at the IETF with OpenAI, Anthropic, Google, and fifty other services already wired in. Two protocols, both real, both growing, neither going away. And every developer building agents that pay for things was rewriting the same payment logic twice. Once per protocol, once per service, once per agent.

Grace Protocol came out of that conversation. We wanted to create one unified interface across all protocols, settled on Solana, on-chain by default.

The work started the next morning.
What you see now is the fruits of our labour, but this is just the start.

Build the future of the agentic economy with us, $GRACE.

We have deployed a fix! Our website is back up.

Sorry for the inconvenience.
