Mapping the Infrastructure Race for Agent-Native Settlement

Every builder in this space eventually asks the same question: which chain should we actually be on? The honest answer is that it's the wrong question, asked too early. Before you pick a chain, you need to separate two things that get conflated constantly: a chain's treasury, and a chain's actual willingness to fund builders. They are not the same signal, and the gap between them is where most teams waste months.

Solvency isn't accessibility

A chain foundation with a nine-figure treasury and no open grants program is worth less to a builder, right now, than a mid-size fund with a live application form and a fast committee. We score every chain on both axes separately: how much capital exists, and how reachable that capital actually is this quarter. The gap between the two tells you more than either number alone.

Program	Ticket size	What makes it reachable
Circle Developer Grants (Arc)	$5K–$100K	Rolling applications, real T-bill-backed yield behind the chain, not a speculative treasury
Base Builder / CDP Grants	1–5 ETH retro, up to $30K	No application for the retroactive track — ship on mainnet and nominate the work
Aptos Payments Grant	$150K + $25K audit credits	Names agent-to-agent payments explicitly as a funding priority
Arbitrum Foundation (Questbook)	$20K–$150K ARB	Enormous DAO treasury that is chronically under-applied-to

The sovereign chains are the signal nobody's pricing in yet

The more interesting frontier is the new stablecoin and payment-focused chains backed by sovereign or balance-sheet capital rather than a venture fund with a ten-year clock, not the well-covered EVM ecosystem funds. A chain backed by a state-adjacent investment vehicle, powering a central-bank-linked stablecoin, has a durability profile that a VC-funded L2 simply doesn't: there's no fund lifecycle forcing a wind-down, and no LP redemption pressure forcing a pivot.

The tell to watch for is whether a funding announcement explicitly earmarks capital for developer incentives, versus a generic "ecosystem growth" line item. The former is an early, formalizable signal: the program usually doesn't exist yet, which means the builders who show up before it's formalized get the best terms.

Every chain on this list has two jobs, not one

The mistake we see most often is treating this list as purely a fundraising map. It's also an integration map. The same chains funding agent-settlement infrastructure are the chains a serious multi-chain wallet needs to support regardless of whether a grant exists, because the builders and the users are going to be there either way. A closed grant program doesn't mean a chain drops off the list; it means that chain moved from "funder" to "integration target," and the two lists should be scored together, not separately.

Concretely: go live at even a basic integration tier on a new chain before there's a formal program, and "we're already live on your chain, here's the explorer link" turns a cold outreach email into a warm conversation. That's a cheaper way to earn a launch-partner relationship than waiting for an RFP.

What we're watching next

Two shifts are worth tracking going into the next two quarters: consolidation among the gasless/privacy L2 experiments (several have already folded into larger L2s rather than launching standalone), and whether any of the major asset managers now active in tokenized real-world assets start funding settlement infrastructure directly rather than only issuing tokenized products on top of it. Either would meaningfully change where the reachable capital sits.

This is our own market observation based on publicly available program information at the time of writing. Grant terms, treasuries and program status change quickly. Verify current details directly with each foundation before applying.
