Adding TRON — and why USDT-on-TRON is everywhere

If you're building anything in emerging markets, you'll find TRON-USDT very quickly. It's the second-largest stablecoin venue by volume, behind only Ethereum, and ahead of Solana, BSC, and Polygon. This isn't the take I expected to write a year ago.

Why TRON-USDT eats:

• Gas fees are predictable and tiny (~$0.30 for a USDT transfer at typical bandwidth).
• Tether issues TRC-20 USDT in massive quantities; it's the de-facto rail for OTC desks in Asia, Africa, the Middle East.
• Wallet UX is roughly the same as ERC-20 USDT, so users don't feel a downgrade.

What we had to build:

• TRON address generation. Different curve than EVM (ed25519 vs secp256k1) and a base58check format. Our HD library supports both; the chain adapter wires the right derivation path.
• Bandwidth and energy accounting. TRON's gas model isn't a flat fee — it's a free quota of bandwidth + energy that you can stake to expand. We default to free-tier behavior; high-volume tenants can stake TRX into our gas vault for higher throughput.
• USDT-specific fast paths in the dashboard. Default chain selection sorts USDT-supporting chains to the top.

If you're building for non-Western markets and you don't support TRON-USDT, you're missing the largest single stablecoin venue your users actually use.
