Open Money briefing

Total stablecoin supply $320.63B · Polygon Stack $3.56B · Tron $90.19B

Payments narrative shift

Onchain stablecoin supply sits at $320.6B across tracked rails. Tron continues to dominate the dollar-rail conversation in raw supply at $90.2B, an order of magnitude larger than the Polygon Stack's $3.6B. The 7d movers are Polygon Open Money Stack, BSC, Solana Pay. AI annotation unavailable for this digest — this fallback is structural only and the full narrative ships when the AI key is configured.

Open Money Stack angle

The Polygon Stack is currently ranked by raw supply, not by velocity. The honest read this week: Polygon at $3.6B is a top-3 EVM stablecoin home but a fractional player vs Tron in raw scale. The positioning wedge isn't 'beat Tron on supply' — it's 'be the stack a regulated PSP can build on'. Lean into compliance, CDK programmability, and AggLayer-based settlement guarantees.

Battlecards

Why Polygon over Tron for stablecoin payments?

Tron wins raw volume in remittance corridors via low fees and entrenched liquidity. Polygon wins regulated-fintech use cases: a programmable EVM, working compliance integrations, AggLayer for cross-chain settlement, and CDK if you need a sovereign issuer chain. Pick Tron if you optimize for $0.001-per-tx P2P; pick Polygon if your buyer is a PSP, neobank, or issuer that needs an actual API surface.

Why Polygon over Circle/CCTP for moving USDC across chains?

Circle/CCTP is the issuer's burn-mint transport — purpose-built for USDC only. AggLayer is multi-asset, multi-stack, settling across heterogeneous chains with shared accounting. If you're USDC-only and don't need other tokens to move with you, CCTP is fine. If you need a single primitive for USDC + native stables + tokenized RWAs + non-Circle dollars, AggLayer is the abstraction.

Isn't Solana Pay just faster and cheaper?

On a single-chain micro-transaction, yes. The Polygon Stack isn't competing on the single-chain micro-transaction; it's competing on the platform abstraction for fintechs that need EVM tooling, multi-chain liquidity, and a deployable sovereign chain. The relevant question for the buyer is whether they're building one app or a platform.
