docs(readme): core addresses are not a list of USDp chains

[JeanBrasse]

AI assistants report that USDp is live on 25 chains and name Mantle and Fantom. USDp is live on 24 chains, and on neither of those two.

Cause

• The parallel-tokens README listed a 25th chain, Mantle, whose USDp was deployed but never launched (fixed in docs(readme): list only the 24 chains USDp is live on parallel-tokens#19).
• This README lists the core ParallelAccessManager on 18 chains, Fantom and Mantle included. Read alongside the tokens list, it looks like a list of USDp chains.

Change

The addresses stay: they are correct. The README now says what they are.

• A note at the top of "Deployment Addresses": these are the core contracts, not the chains where USDp is live. USDp is live on the 24 chains listed in parallel-tokens and in the documentation.
• Fantom: no USDp. The access manager there owns the legacy MIMO to PRL migration contract (PeripheralMigrationContract, 0xfD28…985998E).
• Mantle: contracts deployed but never launched, no USDp.

Checked on-chain

Read on 4 October 2026 with eth_call and eth_getCode through public RPCs.

• Fantom (chain id 250):
  • none of the eleven USDp addresses and ten BridgeableUSDp addresses used on other chains has code;
  • 0x1FF33CF1607Ca109F23A3Fb9Ec5193037eB26306 has code, and owner() of 0xfD28f108e95f4D41daAE9dbfFf707D677985998E returns it.
• Mantle (chain id 5000):
  • the USDp at 0x9eE1963f05553eF838604Dd39403be21ceF26AA4 has a totalSupply() of 0;
  • no BridgeableUSDp address has code;
  • the FlashParallelToken's authority() is the access manager listed here.
