Privacy considerations for AVAX to SOL
Where offered, Private Route is designed to reduce an obvious direct association between the sending wallet and received assets; it does not make AVAX on Polygon or SOL on Arbitrum activity anonymous or invisible. Polygon exposes account history, token approvals, contract calls, logs, gas funding, amounts, and timing under its own chain identifier. Polygon PoS uses an EVM sidechain architecture with its own validator checkpoints and gas balance. Its token representations and bridge behavior are separate from Ethereum L1 even when wallets use the same 0x account. Arbitrum exposes account history, token approvals, contract calls, logs, gas funding, amounts, and timing under its own chain identifier. Its Nitro optimistic-rollup design executes through a sequencer and posts compressed transaction data to Ethereum. L2 inclusion and Ethereum settlement are separate milestones, so a source receipt can advance before the rollup state is final on L1. AVAX is native to the Avalanche primary network and pays C-Chain gas. An AVAX-labeled contract on another smart-contract network is tokenized AVAX rather than the native C-Chain coin. Native SOL pays Solana fees and participates in the Solana account model. Wrapped SOL is an SPL token account representation and tokenized SOL on another network is not native SOL. Token contracts, approvals, wallet reuse, recognizable amounts, close timing, and later consolidation can create association signals. Private routing changes only part of that observable transaction context. Identity-verification requirements are separate and must be checked in the live flow.
What remains visible on Polygon
Polygon exposes account history, token approvals, contract calls, logs, gas funding, amounts, and timing under its own chain identifier. Polygon PoS uses an EVM sidechain architecture with its own validator checkpoints and gas balance. Its token representations and bridge behavior are separate from Ethereum L1 even when wallets use the same 0x account. POL is the native gas asset for Polygon. Reusing the sending address, approval pattern, or recognizable amount can preserve source-side context.
What remains visible on Arbitrum
Arbitrum exposes account history, token approvals, contract calls, logs, gas funding, amounts, and timing under its own chain identifier. Its Nitro optimistic-rollup design executes through a sequencer and posts compressed transaction data to Ethereum. L2 inclusion and Ethereum settlement are separate milestones, so a source receipt can advance before the rollup state is final on L1. Receiving-address reuse, immediate consolidation, and later transfers can create destination-side associations.
Polygon source role versus Arbitrum destination role
A Polygon PoS source uses its validator/checkpoint system and POL gas; its token contracts and checkpoints are separate from Ethereum L1. Those source-side events remain visible. An Arbitrum receipt appears on the Nitro L2 ledger under an Arbitrum token contract or native ETH balance; later spending needs Arbitrum ETH while L1 settlement continues separately. That receipt and later destination activity remain visible.
Polygon and Arbitrum keep separate account histories
The same-looking 0x wallet syntax does not combine the two ledgers. A Polygon PoS source uses its validator/checkpoint system and POL gas; its token contracts and checkpoints are separate from Ethereum L1. On Avalanche C-Chain, native AVAX funds both the transfer value and gas; on another chain, an AVAX-labelled contract behaves as a token input instead. An Arbitrum receipt appears on the Nitro L2 ledger under an Arbitrum token contract or native ETH balance; later spending needs Arbitrum ETH while L1 settlement continues separately. Native SOL receipt uses a Solana address and can fund later fees; wrapped SOL uses an SPL token account and tokenized SOL elsewhere is not native. Rollup inclusion and settlement can also expose different timing milestones.
AVAX native and token representation evidence; SOL fee-payer and account evidence
AVAX is native to the Avalanche primary network and pays C-Chain gas. An AVAX-labeled contract on another smart-contract network is tokenized AVAX rather than the native C-Chain coin. The exact deposit representation, amount, timing, and later wallet activity remain observable. On Avalanche C-Chain, native AVAX funds both the transfer value and gas; on another chain, an AVAX-labelled contract behaves as a token input instead. Those source events remain public. Native SOL balance changes, fee-payer accounts, signatures, and later token-account activity remain visible on Solana. Tokenized SOL elsewhere follows a separate contract ledger. Native SOL receipt uses a Solana address and can fund later fees; wrapped SOL uses an SPL token account and tokenized SOL elsewhere is not native. The receipt and later destination use remain public.
What Private Route changes—and what it does not
Private routing can reduce an obvious link between two EVM accounts, but source approvals, gas, logs, destination contract or native receipt, and later activity remain on separate chain histories. Sequencer and settlement timing can add correlation evidence. A Polygon PoS source uses its validator/checkpoint system and POL gas; its token contracts and checkpoints are separate from Ethereum L1. On Avalanche C-Chain, native AVAX funds both the transfer value and gas; on another chain, an AVAX-labelled contract behaves as a token input instead. An Arbitrum receipt appears on the Nitro L2 ledger under an Arbitrum token contract or native ETH balance; later spending needs Arbitrum ETH while L1 settlement continues separately. Native SOL receipt uses a Solana address and can fund later fees; wrapped SOL uses an SPL token account and tokenized SOL elsewhere is not native.
Verification and provider policy for this exact route
The provider must support the exact L2 direction, asset contracts, amount, and region. Rollup support and privacy routing do not imply that identity verification, account, or custody requirements are absent. A Polygon PoS source uses its validator/checkpoint system and POL gas; its token contracts and checkpoints are separate from Ethereum L1. On Avalanche C-Chain, native AVAX funds both the transfer value and gas; on another chain, an AVAX-labelled contract behaves as a token input instead. An Arbitrum receipt appears on the Nitro L2 ledger under an Arbitrum token contract or native ETH balance; later spending needs Arbitrum ETH while L1 settlement continues separately. Native SOL receipt uses a Solana address and can fund later fees; wrapped SOL uses an SPL token account and tokenized SOL elsewhere is not native.
