Zach Perlman·engineer·Miami, FL
· workshop notes

Senior engineer at Quicknode building blockchain RPC and developer tooling used across the crypto ecosystem. I like things that are fast, small, and a little weird — x402 payment rails, agent arenas, raw-transaction sleuthing, healthcare dashboards that have to clear HIPAA. AI is changing development daily; the work now is finding the safe new tools that level up the LLMs. A lot was possible before; anything is possible now. If you're not using this day-to-day, you're falling behind.

· constructed works

Built the useful.

2026 · TypeScript · Viem

x402-rails

Public package · payment rails for the agentic era

Open-source backbone infrastructure for x402 — programmatic HTTP 402 settlements between AI agents and the services they call. Per-request stablecoin payments without an account, an invoice, or a tab. Free for anyone to drop in.

2026 · TypeScript · Next.js

x402-payments

Public package · drop-in x402 for any API

Open-source SDK that lets a Node or Next.js endpoint quote a price, settle it on-chain, and serve the response — turning any function into an instantly-monetizable agent service. Install, wrap your handler, ship.

2026 · Next.js · Viem

x402playground.com

A live x402 sandbox

Open the page, connect a wallet, watch real x402 calls execute against demo endpoints. The fastest way to see paid HTTP feel like a normal fetch().

2026 · Next.js · TypeScript

agentarena.xyz

Where agents fight for benchmarks

A leaderboard + match runner for autonomous agents — pit different models on the same task, score speed/cost/correctness, share replays. Every invocation is metered through x402.

2026 · TypeScript · Viem

x402pokemon

Pokémon trades over x402

A demo that lets two agents trade Pokémon between each other with x402 settlements between every move. Pure showcase — also genuinely fun.

2026 · Next.js · TypeScript

Wacdonalds

AI burger ops

A weekend project where an LLM runs the kitchen — orders flow in, agents fill them, x402 invoices print for every nugget. Half satire, half genuine experiment in agentic dispatch.

2026 · TypeScript · Viem

Packz

Bundles for autonomous agents

Curated packs of x402-paid services an agent can subscribe to with one signature — research, code execution, rendering, image gen. Buy a pack, give it to an agent, watch it work.

2026 · Next.js · Solidity

Story-block

On-chain interactive fiction

Branching narratives where readers vote on the next chapter with on-chain signals; outcomes get attested as blocks. Blockchain as story-state machine, not as ticker.

2026 · TypeScript · Next.js

Modtech

Modular tech consulting

Sticking-point code review + architecture work for early-stage teams. Drop in for a sprint, leave behind something that's still maintainable a year later.

2026 · Next.js · Postgres (RLS)

Enterprise CMS dashboards

HIPAA-compliant control surfaces

Multi-tenant content + analytics dashboards built to clear HIPAA, SOC 2, and the audit trail every healthcare buyer asks for. Row-level security in Postgres, signed-URL document delivery, full event log.

2026 · TypeScript · Solidity

poc-distribution

Referral fee distribution PoCs

Three parallel proofs-of-concept for scalable on-chain referral payouts: 1inch CumulativeMerkleDrop, Thirdweb Airdrop, and Splits Protocol. Live-tested on Polygon mainnet with gas benchmarks.

2025 · JavaScript · ethers.js

rawTxnAddressFinder

Raw transaction archaeology

JavaScript CLI that decodes raw Ethereum transactions and surfaces the signer address + nonce without needing an RPC. Great for forensics and cold-wallet recovery flows.

2025 · Next.js · MDX

zlerplabs.com

A personal sandbox

Long-running experiments blog — part playground, part portfolio, part accidental README. Runs on Next.js with a custom MDX pipeline and view-transitions-powered post navigation.
