Why Milysec

Built for leaders who buy outcomes, not hype

We are an Australian venture studio at the intersection of AI application development, Solana, and web3. We ship systems that handle real users and real money — then stick around when it matters.

Over a decade across fintech, SaaS, AI, and blockchain. Production launches — from stablecoin infrastructure to agentic payment rails.

Ship faster

Small senior team. Modern stack. No theatre — production systems in weeks, not quarters of process.

Built for real money

Payments, stablecoins, and agent rails with the compliance awareness Australian businesses need.

Studio, not a body shop

We co-build products and run our own ventures. You get builders who think like owners.

Engagement

How we work

Simple path from first conversation to production software.

Scope the outcome

A short call on the problem, users, and constraints. You leave with a clear build path — or an honest no.

Design & build

Architecture, UI, and implementation in tight loops. You see working software early, not a 40-page deck.

Launch & operate

Ship to production, hand over cleanly, or keep us on as the technical co-founder for the next phase.

Stripe MPP, Tempo, and x402 on Solana: which rail for Australia

Stripe and Tempo co-authored MPP so agents can pay over HTTP 402 with cards or Tempo stablecoins. x402 does the same job with permissionless stablecoins, often on Solana. Here is how an Australian builder should pick, and what we run on Milypay.

Airwallex vs Stripe vs x402 for Australian agent payments

Airwallex and Stripe both want to be the account layer for agentic commerce. x402 is a different bet: HTTP 402 and a wallet, often on Solana. For Australian teams the split is FX, AUD, and whether the buyer is a Stripe/Airwallex customer or an agent with coins.

Milypay + MoneyGram: Funding the Wallet Before the 402

x402 fails when the agent wallet is empty. MoneyGram does not settle Milypay calls — it on-ramps USDC so the agent can. Here is the problem, the integration, and the loop we shipped.
