This entry sits under systems index. Read it against CCTP V2 overview · Circle USDC cross-chain burn-and-mint for peer / contrast context and fintech index for the broader system / regulatory boundary.

Key facts

  • JPM Kinexys explicitly states that in 2026-01 it will not integrate CCTP V2 (kinexys/technology.md §4.2)
  • CCTP V2 is the settlement infrastructure for the public-chain coalition(Circle + Arc + 18 chains)
  • Canton is the settlement infrastructure for the private-chain coalition(GS + BNY + JPM + DTCC)
  • Arc chain is the native home of CCTP V2 , and USDC is Arc’s gas

Mechanism / How it works

The fundamental differences between the 2 routes:

DimensionCCTP V2(public-chain route)Canton(private-chain route)
Liquidity sovereigntyCircle-only mint/burnLedgering inside the bank consortium
Cross-chain methodburn-and-mint(no wrapped asset)DAML application-to-application atomic calls
PrivacyFully public on public chains + denylist filterSub-transaction privacy by default
Value attributionCircle + public-chain ecosystemBank consortium(GS/BNY/JPM/DTCC)
Supervisory modelCircle self-compliance + §501 denylistBuilt-in Regulator Node
User typeCrypto-native + some institutionsPure institutional customers

JPM Kinexys’s choice:JPMD does not integrate CCTP V2 and returns to Canton — the reasons are (1) Coinbase Custody customers’ holdings on Base can be reverse-inferred through chain analysis; (2) Canton natively supports multi-party atomic settlement; (3) DAML is better suited to financial contracts than Solidity; (4) JPM is a founding Canton member, creating strategic alignment.

Circle Arc’s choice:Arc chain directly bets on CCTP V2 + USDC as gas + the §501 compliance narrative, avoiding profit-sharing with Coinbase Base($200M/year) — this is the core measure in Circle’s de-Coinbase strategy.

Origin & evolution

2024-2025 年 has entered the window period for institutional tokenization route selection. The Circle route(CCTP V1 → V2 → Arc) and the JPM route(JPMD on Base → JPMD on Canton) evolved in parallel, but in opposite directions. In 2026-01 , JPM publicly announced that it would move its main battlefield to Canton, formally standardizing the public / private chain split.

Expected next 5 years:the public-chain route(CCTP V2 + Arc + Base + BlackRock BUIDL) leads crypto-native + DeFi + cross-border retail; the private-chain route(Canton + JPMD + GS DAP + BNY LiquidityDirect) leads institutional collateral management + large-value settlement. The 2 route forms parallel systems inside the “US dollar compliance zone” under the constraints of §501 entry-list jurisdiction clauses(see The Blockchain Industry Has Split at the DNA Level into \"On-Chain Finance\" and \"Crypto\").
