$MAXIM is now live on Solana.

Maxim Protocol is a single payment system that lets AI agents pay for things on their own, no matter which payment standard a service uses behind the scenes. It gives developers an easy way to set up a wallet for each agent, control how much it can spend, and see every payment it makes on a clear, verifiable record.

Maxim Protocol Security Audit Underway
We're pleased to confirm that an independent security firm has been engaged to conduct a full audit of Maxim Protocol and its on-chain smart contracts. The review begins today.
The audit covers the complete Anchor program: agent wallet registry, on-chain spend-policy enforcement, payment settlement, and the protocol-level safety controls. The contracts remain on devnet and will not be promoted to mainnet until the audit is complete and findings are addressed.
The auditor will be named alongside the published report once the engagement concludes.

Think of Maxim Protocol as a debit card and a spending limit for your AI agents. We're building the system that lets an agent pay for what it needs to get a job done, while you decide the budget, the rules, and get a full, transparent history of where every cent went.

Our SDK is live, and our first integration partner is coming aboard: @footymarketxyz.
Footymarket is a football prediction market protocol on Solana. Positions are SPL tokens settled in USDC, which makes them a natural fit for agents that hold Solana wallets and pay through Maxim Protocol. Their team reached out 1 day after our SDK launched, and they are first through the door.
Agents provisioned through Maxim Protocol will be able to buy and sell Footymarket positions directly, under enforced spend policies, with every trade settled on-chain.
Proud to have them as our first. More integration partners to come.

We are partnering with @maximprotocol to bring autonomous AI agents to Footymarket.
Maxim Protocol is the cohesive payment rail for AI agents: one SDK, native support for both x402 and MPP, every transaction settled on Solana. By integrating their infrastructure, agents provisioned through Maxim Protocol can buy and sell positions on Footymarket directly, funding trades from their own non-custodial wallets under enforced spend policies.
Footymarket positions are collateralised in USDC. Maxim Protocol agents already hold Solana wallets and settle in USDC. The two fit together cleanly: an agent can take a YES or NO position the moment its model updates, with every trade recorded on-chain.
This is football markets priced not just by people, but by autonomous agents reasoning over data in real time. Rolling out this next in our beta.

We are building Maxim Protocol to support x402 properly, so it means something to see the work noticed by the coauthor of the x402 whitepaper, @kleffew94!
Heads-down on the build.

The Maxim Protocol program is now at v2 on-chain. The protocol config account gained a version field that mirrors the program revision, so off-chain clients can assert they're talking to the expected program before submitting a transaction.
The global single-payment cap from the prior commit is now fully wired into protocol state.

Contracts update: monthly budget caps enforced on-chain alongside daily and weekly, an admin global payment cap as an incident-response lever, plus optional settlement memos for tying payments to workflow IDs and an idle-agent timestamp.

The interesting agent systems aren't single agents, they're agents hiring other agents. That only works if spend stays bounded and the money trail stays intact across hops.
Maxim Protocol caps a sub-agent's budget at invocation and records every hop on-chain, so a delegated task can't quietly overspend.

Supporting two payment standards by hand means two integrations, two things to maintain as each spec changes.
Maxim Protocol collapses that into one interface that tracks both, so the maintenance burden of a fragmenting standards landscape stops being yours.

The fear with an autonomous agent isn't that it pays for the wrong thing once. It's that it does so a thousand times before anyone notices. Maxim Protocol enforces budget caps, per-call limits, allowlists, and rate limits at the infrastructure layer, so an agent's worst case is bounded before it ever runs.

We're not trying to make the agent. We're making the thing the agent stands on. Provisioning, routing, settlement, and policy enforcement, handled, so the interesting work happens a layer up. Boring infrastructure is the point.

The blocker on autonomous agent spend usually isn't the agent, it's that finance can't see what it did.
Maxim Protocol writes every payment to Solana with protocol, amount, counterparty, and timestamp. Approving an agent fleet gets easier when every dollar it moves is already reconciled on-chain.

Betting on x402 or MPP winning is a bet you don't need to make. Maxim Protocol supports both behind one interface, so your agent keeps working regardless of which standard a given service adopts, and regardless of which one wins. Protocol risk becomes someone else's problem.

An agent that can call any API still can't pay for most of them. Payment is the missing primitive in the agent stack: every gated service expects a different scheme, and rebuilding that logic per integration is where projects stall.
Maxim Protocol is the layer that makes "pay for this" a solved call.

We're publishing the design for $MAXIM token utility. It's the roadmap for how the token will plug into Maxim Protocol, in the order we intend to build it, shared now so it's in the open rather than announced as a surprise later.

Next, staking to scale. The API already has per-account rate limits and quotas, and staked $MAXIM will raise an account's ceiling. One firm rule in the design: staking only ever lifts limits, it never gates base access. Pay-as-you-go keeps working with zero tokens held. Stake to scale, not to enter.

Last and most involved: on-chain governance. Token-weighted votes over real protocol parameters, the high-value enforcement threshold, default policy templates, which new payment standards get handler priority, and treasury allocation. This ships only once those parameters genuinely move from admin control to a vote. Real governance or none.

New in the Maxim Protocol docs: a consolidated error reference. Every API error in one place, with its HTTP status, machine-readable error code, and a worked JSON example. Payment, auth, rate-limit, and idempotency errors all documented so your agent can branch on exactly what went wrong.
