Increase Easy Track transfer limits for Liquidity Observation Lab to align with EGG

TL;DR

The Lido Ecosystem Foundation (the "Foundation") proposes updating the Easy Track setup for transfers to the Liquidity Observation Lab (LOL) multisig:

• increase the stETH transfer limit from 6K stETH to 8K stETH per 6 months;
• introduce a dedicated stablecoin Easy Track payment factory with a limit of $8M per 6 months.

The proposed update does not introduce any additional budget allocation beyond the previously approved funding.

Rationale

Under the current Easy Track configuration, transfers to the LOL multisig are constrained by existing limits and the available payment contract set. Following approval of the LDO accumulation program, LOL is expected to handle an increased flow of funds as it executes the approved mandate, which requires higher stETH transfer bandwidth. At the same time, the absence of a stablecoin Easy Track payment factory introduces unnecessary operational overhead for stablecoin-denominated operations, requiring manual swaps and imposing an ongoing operational burden.

This proposal addresses both issues by increasing the stETH transfer limit and introducing a dedicated stablecoin payment factory, aligning the Easy Track configuration with current operational needs while preserving existing budget constraints and governance controls.

Proposed changes

The Foundation proposes to update Easy Track transfer limits for funding the LOL multisig 0x87D93d9B2C672bf9c9642d853a8682546a5012B5:

1. Increase the transfer limit on the existing LOL stETH Easy Track payment factory 0x1F2b79FE297B7098875930bBA6dd17068103897E from 6K stETH to 8K stETH per 6 months.
2. Introduce a new LOL stablecoin Easy Track payment factory (with corresponding add/remove allowed recipients Easy Track factories) to allow stablecoin transfers with a limit of $8M per 6 months. The new contract addresses are to be published on the Research forum after deployment.

Subject to community support, the proposed changes will be submitted for on-chain implementation via an Aragon vote.
