Agent infrastructure
Arka
Rust tooling for blockchain agents. The July update adds a Solana chain module; the project also exposes agent primitives over MCP.
Est. 2015
Hard problems in decentralized systems, from science to shipping.
We build blockchain and agent infrastructure, from open-source foundations to commissioned implementations. Bring us a hard problem, a funded brief, or a product worth building together.

Open-source foundations. Implementations people can use.
Selected projects with a clear path from technical work to a paid deployment.
Featured implementation · agent payments
Switchboard
Integrate payments into an agent workflow: paid API access, escrow, spending controls, and settlement. Open-source Python tooling and Solidity contracts provide the starting point.
A concrete first engagement
One workflow. End to end.
Agree the payment rail, integrate one paid endpoint or escrow flow, exercise failure and refund paths, and hand over tests and an operating runbook.
Scope, deployment readiness, and acceptance criteria are agreed before work starts.
Liquidity research
Meridian & Quoter
Market-making and backtesting foundations for a commissioned simulation, venue adapter, or execution workflow.
Stablecoin infrastructure
Issuance & monitoring
Build on stablecoin-toolkit and depeg-monitor for a scoped issuance prototype, reserve dashboard, or alerting integration.
These are open-source implementations and starting points for commissioned work. Product ventures develop through paid pilots, repeat use, and a dedicated team. Our approach to ventures →

Research areas
What we publish and ship, mapped to the repos and briefs we maintain in the open.
On-chain agents & automation
Autonomous market-making for illiquid and RWA markets, multi-chain execution, and shared infra for wallets, payments, and agent-to-agent settlement.
meridian · monsoon · scout · switchboardStablecoins & peg resilience
Modular issuance, reserves, compliance hooks, and live monitoring when pegs drift, grounded in run-risk and market-structure research.
stablecoin-toolkit · depeg-monitorDeFi execution & L2 economics
Agentic quoting and inventory-aware MM; L2 fee prediction after EIP-4844 blob markets for wallets and protocols.
quoter · gas-oracleRWA & AI-native token standards
Geography-aware RWA patterns and reference assets; on-chain provenance and transfer rules for model-weight artefacts.
stablecoin-toolkit · erc721-aiAuditability & secure SDLC
Executable checks in Foundry for the vulnerability classes we see in production: reentrancy, oracles, upgrades, flash loans, access control.
audit-checklistPublished research & briefs
Quarterly briefs and notes across L2 scaling, stablecoins, DeFi, MEV, ZK costs, and RWA, written to be cited, funded, and built on.

monsoon
Autonomous airdrop farming framework. Multi-wallet, multi-chain, eligibility scoring, and campaign planning. Powered by scout.
Bring us a problem worth solving.
Three ways to work with kcolbchain. Scope and commercial terms are agreed privately.
For teams
Commission work
Agent payments, protocol integrations, technical reviews, and research with a defined deliverable. Agree scope and price privately, then start against funded milestones.
For ecosystems
Build with a partner
Fund a reference implementation, an integration programme, or a delivery team around a specific adoption problem.
For investors
Diligence & ventures
Commission technical diligence or portfolio engineering. Discuss product ventures emerging from implementations and repeat customer demand.
Community & network
A high-signal magnet for builders, founding teams, and capital partners, tied together by open repos, research, grants, and long-horizon work (not hype cycles).
Developers & contributors
Live list of open invitations across every repo. One merged PR gets you on the contributors page; the Fellow tier (5+ merged PRs) is our first-invite pool for paid research and partner work.
github.com/kcolbchain · invitations · join flowFounders & operators
Protocol leads and CXOs use our research and engineering embeds for roadmap risk, launches, and board-ready briefs. Email with context and we route fast.
krishna@kcolbchain.comInvestors & ecosystem funds
Co-funded research, sponsored briefs, and grant-aligned milestones. We publish in the open so diligence and ecosystem narratives stay grounded in artefacts.
Collaborate & grantsOn-chain identity (roadmap)
Optional wallet-linked profiles, contributor credentials, and NFT-style attestations for alumni and partners, designed for sybil resistance and privacy, not vanity drops.
rolling out with core contributors firstOur approach
Research that ships. Credibility that compounds.
01
Hypotheses as software
We treat codebases as falsifiable claims: runnable prototypes, benchmarks, and repeatable experiments.
02
Open by default
We publish artefacts, notes, and learnings, building thought leadership, attracting collaborators, and enabling grants.
03
Systems-level rigor
Performance, adversarial modeling, and engineering constraints are first-class because protocols fail in the real world.
04
Partnership-driven impact
We plug in as senior protocol and infra capacity: design reviews, implementation on the critical path, and research programs that feed directly into your roadmap.

Community
The contributor flywheel is live: ladder, invitations, and how paid work routes
Newcomer → Regular → Fellow is codified, invitations refresh daily, and the money loop is explicit. Here's how an OSS collective sustains the people building it.

The agent payment wars: x402, MPP, AP2, and where switchboard fits
Four competing agent-payment standards launched in one month. We mapped them all and found the gap none of them fill.

meridian: agents for RWA and long-tail liquidity
Why pool-based AMMs fail for many RWAs and how autonomous quoting agents plus backtesting change the picture.
