Polymesh is a purpose-built Layer 1 blockchain designed exclusively for regulated financial securities — not a general-purpose chain retrofitted with compliance tools, but a blockchain where identity verification, investor eligibility rules, corporate actions (dividends, splits), and finalized settlement are native primitives. Built by Polymath (a tokenized securities pioneer) and backed by institutions including Tokeny, Grayscale, and CoinFund, Polymesh solves the core problem of issuing securities on public blockchains: regulatory requirements (KYC, accredited investor checks, transfer restrictions) conflict with pseudonymous, permissionless design. Polymesh requires all participants to have verified on-chain identities (via Customer Due Diligence providers) before interacting — and securities smart contracts (Security Tokens) enforce transfer rules automatically. POLYX pays gas, secures the network via NPoS staking, and governs protocol upgrades.
How It Works
Permissioned identities:
Every Polymesh user has an on-chain identity (DID — Decentralized Identifier) verified by accredited Customer Due Diligence (CDD) providers. This gives issuers certainty that their token only transfers to verified, eligible investors — a requirement for securities laws in most jurisdictions.
Security Tokens (STs):
Security tokens on Polymesh define compliance rules as parameters:
- Which jurisdictions are eligible investors
- Maximum investor counts
- Lock-up periods
- Minimum investment sizes
These rules are enforced at the protocol level automatically on every transfer attempt.
Corporate actions:
Polymesh has native support for corporate events — dividend distributions, stock splits, and capital raises — which can be encoded and executed on-chain rather than requiring off-chain intermediaries to compute proportional distributions.
Settlement:
Polymesh uses “affirmed settlement” — both counterparties must confirm a transfer before it executes, enabling atomic delivery-vs-payment settlement without custodians.
NPoS consensus:
Validators are permissioned (must have verified identities) but POLYX holders nominate which validators they trust — combining Polkadot-style NPoS with regulatory accountability.
Tokenomics
| Metric | Value |
|---|---|
| Supply | Inflationary (NPoS staking emissions) |
| Staking | POLYX stakers nominate validators and earn rewards |
| Gas | POLYX burned as transaction fees |
| CDD provider fees | Paid in POLYX to identity verifiers |
| Treasury | Community-governed development fund |
Use Cases
- Gas — POLYX pays all transaction fees on Polymesh
- Staking — Nominate validators and earn inflation rewards
- CDD provider payments — Identity verification services collect POLYX fees
- Governance — POLYX holders vote on protocol upgrades and treasury allocations

Common Misconceptions
“Polymesh is a private blockchain because it requires identity.” Polymesh is a public blockchain — anyone can view transactions on the explorer. Identity requirements apply to participants (investors, issuers), not observers. The chain is not “permissioned” in the sense of restricted access for block production.
“POLYX will be replaced once securities move to Ethereum.” Polymesh’s value proposition is built-in securities rails (corporate actions, settlement, CDD identity) that Ethereum fundamentally lacks at the protocol level. Retrofitting Ethereum with those features via smart contracts creates complexity and legal ambiguity; Polymesh bakes them in natively.
