Coinbase has opened trading of four cryptocurrency tokens — Aethir (ATH), Raydium (RAY), PolySwarm (NCT), and Starknet (STRK) — to residents of New York State, the exchange announced on March 21, 2026. The expansion is significant because New York maintains one of the most stringent cryptocurrency regulatory frameworks in the country through its BitLicense regime administered by the New York Department of Financial Services (NYDFS).

Each token listed in New York requires specific NYDFS approval — either through a formal green-listing process or as part of a licensed exchange's approved asset roster. The addition of these four tokens signals continued, if incremental, regulatory progress between Coinbase and New York's financial regulator.

Aethir (ATH) — Decentralized GPU cloud infrastructure network; enables AI and gaming compute at scale
Raydium (RAY) — Automated market maker (AMM) and liquidity protocol built on the Solana blockchain
PolySwarm (NCT) — Decentralized threat intelligence marketplace for cybersecurity professionals
Starknet (STRK) — Ethereum Layer 2 validity rollup using STARK-proof cryptography for scalable, low-cost transactions
Effective date: March 21, 2026
Jurisdiction: New York State residents only (BitLicense requirement)

Why New York Listings Are a Big Deal

New York's BitLicense framework, introduced in 2015, requires any company offering cryptocurrency services to New York residents to obtain a license from the NYDFS — and then get separate approval for each digital asset offered to those customers. This means that while a token may be freely tradeable on Coinbase in 49 other states, it cannot be offered to New York users until it clears a specific NYDFS review covering its use case, technical structure, legal status, and anti-money laundering compliance.

The result is that New York crypto listings lag behind the rest of the country — often by months or even years. Tokens that become available nationally may sit in NYDFS review limbo for extended periods, frustrating New York-based retail and institutional traders who are shut out of markets their counterparts elsewhere can access freely. When Coinbase announces a New York expansion, it represents the conclusion of a bureaucratic and regulatory process that goes well beyond a standard exchange listing decision.

The Four Tokens: What They Do

Aethir (ATH) — Decentralized GPU Cloud

Aethir is a decentralized cloud computing network that aggregates enterprise-grade GPU capacity — primarily from data centers and telecom operators — and makes it available on-demand for AI inference, cloud gaming, and virtual desktop infrastructure. The ATH token powers the network's payment layer, validator rewards, and governance. Aethir has positioned itself as a direct competitor to centralized GPU cloud providers at a time when GPU capacity is among the most constrained resources in the AI boom.

Raydium (RAY) — Solana's AMM

Raydium is the largest automated market maker on the Solana blockchain, providing on-chain liquidity pools and decentralized exchange functionality. RAY tokens are used for staking, governance, and fee sharing within the protocol. Raydium benefits directly from Solana's activity levels — as Solana's DeFi and memecoin trading volume rises, Raydium's fee revenue and RAY token utility increase proportionally. Its listing in New York gives New York-based Solana ecosystem participants direct access to the ecosystem's core liquidity infrastructure.

PolySwarm (NCT) — Cybersecurity Intelligence Network

PolySwarm is a decentralized threat intelligence market that incentivizes security researchers, antivirus engines, and cybersecurity firms to compete to identify and classify malware and malicious files for businesses and governments. The NCT (Nectar) token is the network's utility currency, used to submit files for analysis and reward security experts whose verdicts prove accurate. With cybersecurity spending at record levels globally, PolySwarm occupies a niche that bridges traditional enterprise security and decentralized market design.

Starknet (STRK) — Ethereum Layer 2

Starknet is one of Ethereum's most technically sophisticated Layer 2 scaling solutions — a validity rollup that uses STARK zero-knowledge proofs to batch thousands of transactions into a single cryptographic proof submitted to Ethereum mainnet. The result is dramatically lower fees and higher throughput while inheriting Ethereum's security guarantees. The STRK token is used for gas fees on the Starknet network and for staking in the network's decentralized sequencer system. Starknet's New York availability is particularly notable given institutional and developer interest in zero-knowledge cryptography as a scalability and privacy solution for financial applications.

Coinbase and New York: An Ongoing Regulatory Relationship

Coinbase has held a New York BitLicense since 2017 and has incrementally expanded its New York-approved asset list over the years. The exchange has at times been in tension with NYDFS — facing enforcement actions and accusations of compliance lapses — but has maintained its license and continued to invest in the New York market, which represents one of the largest concentrations of retail and institutional crypto activity in the United States.

The March 21 listing announcement comes during a period of relative regulatory calm between Coinbase and federal and state regulators. The SEC's crypto enforcement posture has softened under the Trump administration, and NYDFS has continued processing BitLicense asset approvals at a steady pace. For Coinbase, growing the New York-accessible token roster is both a competitive necessity — rival exchanges are also expanding their New York listings — and a demonstration of its regulatory compliance investment to institutional clients who prioritize regulatory standing.
