On 16 February 2025, CurioInvest teased: Jamton is our upcoming flagship, revolutionizing cross-chain interoperability. The post was short — basically 'private message us.' Six months later, Jamton went live on TON mainnet (the post from June 16, 2025 in this list).
The problem Jamton solves
A tokenised receivable is, fundamentally, a ledger entry on a chain. Different chains serve different audiences:
- EVM (Polygon / Ethereum): institutional DeFi users, deep liquidity, smart-contract composability. This is where the $11B+ in private credit tokenization lives.
- TON (Telegram): 1B+ users, mobile-first UX, growing DEX ecosystem. This is where the retail distribution surface lives.
The challenge: these two worlds don't naturally talk. An investor in Telegram Wallet can't buy a CMTAT on Polygon. A Polygon DeFi user can't reach a Telegram user. Jamton is the bridge.
The architecture
Jamton is a two-sided bridge:
1. EVM side: a standard CMTAT v3.0.0 on Polygon (or Ethereum, or Base, or Arbitrum — any EVM chain). The CMTAT's RuleEngine is the Swiss-DLT rule. 2. TON side: a Jetton (TON's token standard) that wraps the CMTAT. The Jetton's metadata points at the underlying CMTAT on EVM. 1 Jetton = 1 CMTAT. 3. Bridge: a relayer that watches the CMTAT's TransferWithData events on EVM, and mirrors them as Jetton transfers on TON. The relayer is a 2-of-3 CurioInvest multisig.
What this looks like for a user
A retail investor with a Telegram Wallet can buy a tokenised share of, say, an AlpenFreight receivable. The flow:
1. Investor pays USDT (TON) into the bridge 2. The relayer buys the same receivable on Polygon EVM (via the institutional market) 3. The relayer mints a Jetton on TON that wraps the Polygon-side CMTAT 4. The Jetton shows up in the investor's Telegram wallet, with a link to the underlying CMTAT
Same asset, two surfaces, one compliance layer. The Swiss DLT-Act framework, the CMTAT v3.0.0 audit, the FINMA licensing — all of it applies to both sides.
What this means for a CFO
For a CFO doing a 26Q1 issuance on Polygon, Jamton is the optional add-on that gets you 1B+ Telegram users. The cost is small (Jamton is a 2-3% fee on the bridged volume); the upside is distribution surface no other vendor offers.
The current state
As of late 2025, Jamton is live on TON mainnet. The first institutional pilot bridging from Polygon to TON is scheduled for 26Q1. The retail front-end is in development; CurioInvest expects it in 26Q2.
For a CFO in 2026, the question is: do I want my receivables on Polygon only, or do I want to add TON distribution? Adding TON distribution is a 2-week integration. Skipping TON distribution is a missed retail market. The decision is yours.
