docs: Parallelizer and bridge parameters per PIP-69, including Base USDC

[JeanBrasse]

The docs listed the Parallelizer and Bridging Module parameters from before PIP-69 (adopted 24 May 2026): a 100,000,000 mint cap on every asset, a 20% to 95% band on the yield-bearing assets, no USDC on Base, and bridge limits of 2,500,000 USDp a day and 10,000,000 in total. This PR brings them in line with what the chains show today, and cites PIP-69 where it is the source.

Commits:

• 231e660: USDC on the Base Parallelizer;
• 5ca2139: mint caps, exposure bands and mint status on all four Parallelizer chains;
• 82cd59a: USDp bridge limits on all 24 chains.

Parallelizer, read on-chain

Read-only eth_call on each ParallelizerUSDp, 5 October 2026: getCollateralList, getCollateralMintFees, getCollateralBurnFees, getStablecoinCap, isWhitelistedCollateral, isPaused, getIssuedByCollateral, getOracle. The exposure band is read from the fee curves: the minimum is where the burn fee jumps to 99.90%, the maximum where the mint fee reaches 100%.

Chain (block)	Asset	Mint fee	Burn fee	Exposure	Mint cap	Mint	USDp issued against it
Ethereum (26,122,035)	frxUSD	0.00%	0.00%	0% to 100%	1,500,000	open	0.36
	sfrxUSD	0.00%	0.10%	40% to 100%	3,500,000	open	90,021
	USDe	0.00%	0.00%	0% to 100%	1,500,000	paused	0.49
	sUSDe	0.00%	0.05%	20% to 95%	3,500,000	paused	101,359
Base (52,182,124)	USDS	0.00%	0.00%	0% to 100%	1,500,000	open	89.53
	USDC	0.00%	0.00%	0% to 100%	1,500,000	open	6,716
	sUSDS	0.00%	0.10%	40% to 100%	3,500,000	open	193,073
Avalanche (96,766,218)	USDC	0.00%	0.00%	0% to 100%	1,500,000	open	0.73
	ygamiUSDC	0.00%	0.10%	40% to 100%	3,500,000	paused	872.75
HyperEVM (47,678,652)	USDe	0.00%	0.00%	0% to 100%	500,000	open	573
	sUSDe	0.00%	0.10%	40% to 100%	1,000,000	open	322,742

On every asset: not whitelisted, burn not paused. Redeem is not paused on any chain. The price feeds and the 86,400 s stale periods match the implementation page, including the three MorphoChainlinkOracleV2 addresses of the composite oracles.

Against PIP-69

Everything matches PIP-69, except:

• USDe and sUSDe on Ethereum. PIP-69 retires them in three steps: block minting, block burning once their backing reaches zero, then remove them from the list. Step 1 is done; burns are still open and sUSDe still backs 101,359 USDp. PIP-69 sets no new parameters for them, so sUSDe keeps its earlier 20% to 95% band.
• ygamiUSDC on Avalanche. Minting is paused on-chain; PIP-69 does not mention it. Burns stay open.

Bridging Module, read on-chain

Read-only eth_call on each chain's BridgeableUSDp, 5 October 2026: getDailyCreditLimit and getGlobalCreditLimit (mint), getDailyDebitLimit and getGlobalDebitLimit (burn), plus getPrincipalToken, getFeesRate and getIsIsolateMode.

On all 24 chains (Arbitrum, Avalanche, Base, Berachain, BNB Chain, Ethereum, Fraxtal, Gnosis, Hemi, HyperEVM, Ink, Katana, Linea, Optimism, Plasma, Plume, Polygon, Scroll, Sei, Sonic, TAC, Unichain, World Chain, X Layer):

Limit	Mint	Burn	Docs before	PIP-69 section VI	PIP-69 Technical Implementation
Daily	250,000	250,000	2,500,000	250,000	1,000,000
Global	1,500,000	1,500,000	10,000,000	1,500,000	5,000,000

The chain matches the figures in PIP-69's section VI, which the docs now cite. PIP-69's Technical Implementation section gives 1,000,000 and 5,000,000 instead; no chain uses them. On every chain the principal token is the USDp address the docs list, the fee rate is 0 and isolate mode is off, as the docs already say.

Change

Parallelizer (5ca2139):

• products/parallel-v3/fees.mdx: the per-asset table (mint caps, bands, closed and paused mints) and the paragraph under it.
• products/.../usdp-and-susdp/implementation.mdx: every asset's mint cap and band, a status line for the three assets not open to minting, and a PIP-69 citation.
• resources/user-guides/mint-usdp.mdx: the collateral table gains a mint cap column; the "100,000,000 mint cap, 20% minimum exposure" sentence is replaced; the maximum-exposure section and the FAQ mention the mint cap and closed or paused mints.
• security/proof-of-solvency.mdx: the 40% to 100% band, the assets being retired, the mint cap range.
• security/risks.mdx: the "Exposure bounds" mitigation.

Bridging Module (82cd59a):

• resources/user-guides/bridge.mdx: the limits table and the "USDp chains and limits" table, 24 rows;
• products/parallel-v3/fees.mdx: the bridging parameters table;
• products/.../usdp-and-susdp/implementation.mdx: the mint and burn limits of all 24 chains;
• security/risks.mdx: the bridge "Limits" mitigation.

Not changed: sUSDe's burn fee on Ethereum reads 0.05% on-chain. The docs keep 0.10%, the burn fee of every yield-bearing asset, pending an update of that parameter.

Checks (head 82cd59a)

• pnpm build, offline: passes, 333 files, 163 pages, sitemap 159 URLs. pnpm generate:sidebar was not run; no page was added.
• pnpm test: 348 passed (32 files).
• pnpm typecheck: passes.
• Links and anchors on the six changed pages: none broken.
• Merges in memory with docs(x402): settle token, settle failure reasons and the new error codes (BAC-381) #32, docs(x402): the settle token, one settlement per payment, metered payments, x402-fetch 0.3.0, x402 0.8.1 and CLI 0.4.1 #33, docs(prl): sPRL2 v2, staking per chain, rewards on Base, MCP 1.4 and the end of the MIMO migration #34, docs: name the 24 USDp chains, and say USDp is not on Fantom or Mantle #35 and docs(prl): supply and burns #36, one at a time and all chained: no conflict. docs(prl): sPRL2 v2, staking per chain, rewards on Base, MCP 1.4 and the end of the MIMO migration #34 also edits fees.mdx (the PRL staking row) and risks.mdx, and docs(x402): the settle token, one settlement per payment, metered payments, x402-fetch 0.3.0, x402 0.8.1 and CLI 0.4.1 #33 edits risks.mdx, in other hunks; both sides survive the merge. None of them touches bridge.mdx.
