About amser
The billing infrastructure stablecoin merchants have been missing.
The billing infrastructure stablecoin merchants have been missing.
Web3 has a payments problem. Not volume theres plenty of that. The problem is billing.
Stripe solved recurring billing for the internet. Nothing has solved it for stablecoins. Every renewal still requires a manual wallet signature. Revenue leaks quietly, teams build workarounds, and customers churn for reasons that have nothing to do with your product.
amser is the billing infrastructure that's been missing. Non-custodial, deterministic, built for the way stablecoin merchants actually operate.

How we built it
Designed for merchants who can't afford gaps
Every architectural decision in amser starts from the same question: what does a merchant need to trust this with their revenue?
Non-custodial by default
User funds never touch the protocol. amser pulls only what's authorized, only when it's due. No vaults, no pooled balances, no unlimited approvals.
Deterministic execution
Every billing window executes exactly once. No double charges, no race conditions, no retries that shouldn't fire. The protocol enforces the rules — not a cron job.
Auditable state
Every subscription, every authorization, every execution is on-chain and indexable. No hidden logic, no off-chain assumptions your team has to maintain.
Why amser exists
Why amser exists
Most attempts to solve recurring payments in Web3 move the problem off-chain. You get a database of "subscriptions", a cron job that fires transactions, and a support queue full of failed renewals.
amser starts from a different premise: authorization should live on-chain, be inspectable by anyone, and execute without human intervention. Users set rules once. The protocol enforces them. Merchants get reliable, predictable revenue — without holding custody or asking for unlimited approvals.

Payments are one outcome of authorization. Subscriptions, access control, and just in time execution are all the same model applied to different surfaces.
Who amser is built for
Who amser is built for
amser is for teams charging in stablecoins who want billing to work the way it does in Web2 — automatically, reliably, without engineering overhead every cycle.
That includes SaaS products on stablecoin rails, infrastructure providers with usage-based fees, membership communities, and any service that needs access to reflect payment status in real time.
If you're building recurring revenue on-chain, amser is the layer you shouldn't have to build yourself.

If you're building recurring revenue on-chain, amser is the layer you shouldn't have to build yourself.
Authority should be explicit, bounded, and revocable.
amser is building toward that standard for recurring payments and just in time transactions.

amser is in active development on Base. If you're running stablecoin subscriptions or thinking about it, we would love to talk.
