Privacy considerations for AVAX to LINK
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 LINK on Base 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. Base exposes account history, token approvals, contract calls, logs, gas funding, amounts, and timing under its own chain identifier. It is an OP Stack optimistic rollup that batches L2 execution and settles to Ethereum. The same 0x wallet can display different balances on Base and Ethereum, and a token contract on one chain does not identify the representation on the other. 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. LINK is an oracle-network utility token represented by network-specific contracts. It is not the gas asset on Ethereum or EVM rollups, and bridged LINK contracts require separate verification. 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 Base
Base exposes account history, token approvals, contract calls, logs, gas funding, amounts, and timing under its own chain identifier. It is an OP Stack optimistic rollup that batches L2 execution and settles to Ethereum. The same 0x wallet can display different balances on Base and Ethereum, and a token contract on one chain does not identify the representation on the other. Receiving-address reuse, immediate consolidation, and later transfers can create destination-side associations.
Polygon source role versus Base 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. A Base receipt belongs to the Base L2 balance and token contract, not Ethereum L1; later activity needs ETH specifically on Base. That receipt and later destination activity remain visible.
Polygon and Base 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. A Base receipt belongs to the Base L2 balance and token contract, not Ethereum L1; later activity needs ETH specifically on Base. LINK arrives as a network-specific contract balance. The wallet still needs the destination native asset before it can transfer or approve LINK later. Rollup inclusion and settlement can also expose different timing milestones.
AVAX native and token representation evidence; LINK approval and governance-token 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. Token allowances, contract transfers, voting or utility interactions, source gas, and later wallet consolidation can remain visible for this receipt. LINK arrives as a network-specific contract balance. The wallet still needs the destination native asset before it can transfer or approve LINK later. 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. A Base receipt belongs to the Base L2 balance and token contract, not Ethereum L1; later activity needs ETH specifically on Base. LINK arrives as a network-specific contract balance. The wallet still needs the destination native asset before it can transfer or approve LINK later.
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. A Base receipt belongs to the Base L2 balance and token contract, not Ethereum L1; later activity needs ETH specifically on Base. LINK arrives as a network-specific contract balance. The wallet still needs the destination native asset before it can transfer or approve LINK later.
