[https://github.com/BalancerMaxis/multisig-ops/pull/263](https://github.com/BalancerMaxis/multisig-ops/pull/263) ### Motivation Balancer contributors have recently been exploring ways to increase non-toxic flow through the protocol. In the wake of BIP-295’s approval discussions have been in progress with 1inch to bring this discount to 1inch Fusion. This would be done by granting the role for calling `setSwapFeePercentage` to the 1inch Labs settlement contract - then they would pass in interactions which lower the fee on the pool, execute the swap, then return the fee to the previous value. The swap fee could be lowered in this manner by up to 80% to enable a significant increase in “good flow” to Balancer pools. Since Fusion is also available on L2’s we can extend this discount to Arbitrum and Polygon as well. Most of Balancer’s protocol fees are generated from yield rather than swaps. There is a chance this proposal leads to more swap fees but even if it does not, one of the most important goals for the Balancer ecosystem is to grow our DEX volume market share. This is likely one of the best chances we have to move the needle on that. ### Risks The Maxis will retain the ability to call `setSwapFeePercentage` on all pool factories so if something unexpected happens and fees are dramatically lowered or raised globally by accident it can be fixed very quickly by the Maxis. Governance can also revoke this role at any time in the future through a future BIP. ### Specification > **Ethereum** > > If approved, the DAO Multisig `eth:0x10A19e7eE7d7F8a52822f6817de8ea18204F2e4f` will interact with the Authorizer `0xA331D84eC860Bf466b4CdCcFb4aC09a1B43F3aE6` and call `grantRoles` with the following arguments: > > Roles: `[0x3697d13ee45583cf9c2c64a978ab5886bcd07ec2b851efbea2fced982b8f9596,0xc065d550fa98abc242b6baf98e7b2063590675f1ddd81bdb9ea8d8f5c5d52f98,0x7b09f4b61ccfe85436161b0223489b187d9f9158c542b5e6105df147afc78aca,0x15d3918ca8f9895d8906a780f5f402d32707bada7b1b5e7b21b7351257103a35,0xcf5e03a737e4f5ba6d13e23f893a1e0255b362d8ce22e9568e1565fcf92789c7,0x6c3a14f10cbcc5a3f4d0e4e8ad279e7a842735ab188e2b13fb84c6542cc3320c,0x78e9adfe5f05d7114a59d0870d78971192f871f57bb36e2aff2edbe75d425844,0xdee20d81c6075dcc437dbaaf02d316ab255cfcae4a154e04b17abdebc70a5b48,0xd8638fc873fb8c5c0e67c437099a19eb0546fb439dab8babff44196f11d44831,0x1a88f724f61d4985675e65a2ba85b2a985d250dac00d27e06303f4cdabc906ae,0xa5547190e3d59f2bfeb4174ca3454b2f2acaeed644bc7ad7018014516f73f2bd,0x0acc45f3ac7c04369514ee383aad82d5c1eef484fbf9ca5f6d87ad5c5859da40]` > > > **Which correspond to the roles for calling \`setSwapFeePercentage\` on the following pool factories** > > > > WeightedPool v1 > > > > WeightedPool2TokensFactory > > > > Stable Pool v1 > > > > Metastable > > > > Stable Pool v2 > > > > ComposableStablePool > > > > WeightedPool v2 > > > > ComposableStablePool v2 > > > > WeightedPool v3 > > > > ComposableStablePool v3 > > > > WeightedPool v4 > > > > ComposableStablePool v4 > > Account: `0xad3b67bca8935cb510c8d18bd45f0b94f54a968f` > > Which corresponds to the address for 1inch Labs’ Fusion resolver. > **Polygon** > > If approved, the DAO Multisig `matic:0xeE071f4B516F69a1603dA393CdE8e76C40E5Be85` will interact with the Authorizer `0xA331D84eC860Bf466b4CdCcFb4aC09a1B43F3aE6` and call `grantRoles` with the following arguments: > > Roles: `[0x3697d13ee45583cf9c2c64a978ab5886bcd07ec2b851efbea2fced982b8f9596,0xc065d550fa98abc242b6baf98e7b2063590675f1ddd81bdb9ea8d8f5c5d52f98,0x7b09f4b61ccfe85436161b0223489b187d9f9158c542b5e6105df147afc78aca,0xce2ff98f438259b5f78b8cf5818e70fcc2ff35b13dc38356616b1431cea9726e,0xec5cf9ce37bce68429403f673d6dfd0a89d33d4af5960016f9a1bbd07c71be88,0xdb0c4ed39b25abe74530d93d30f2b418aca586eeb088f33f8e60a329c85ab416,0xa301b9c1ebd296e579cdbb2d99698e23f8197f41880e33215a5936b204b2b971,0x0cdf946c050f680a2bbec467e09e41ceaf108b331b1d5b902c9fa45f9e2d944a,0xdee20d81c6075dcc437dbaaf02d316ab255cfcae4a154e04b17abdebc70a5b48,0x22f3e304ab030be776b205711d7ba79f146b07726b10c5e9d29c24dacc09c140,0xf6c13c09ddba8f114fe2b23ff442766dca7a9bf303adfde386f20ac38c749733,0x0ad9662eb9978d490b9f9bc897a15af8892817d0c299cb8ec0c624cccd6b192d,0xdc4f292a9c37b8bfbaf2dc78ff4d2a53114e770bcb186a21957939f01ffbfe6b]` > > > **Which correspond to the roles for calling \`setSwapFeePercentage\` on the following pool factories** > > > > WeightedPool v1 > > > > WeightedPool2TokensFactory > > > > Stable Pool v1 > > > > Metastable > > > > Stable Pool v2 > > > > ComposableStablePool > > > > WeightedPool v2 > > > > ComposableStablePool v2 > > > > WeightedPool v3 > > > > ComposableStablePool v3 > > > > WeightedPool v4 > > > > ComposableStablePool v4 > > Account: `0xad3b67bca8935cb510c8d18bd45f0b94f54a968f` > > Which corresponds to the address for 1inch Labs’ Fusion resolver. > **Arbitrum** > > If approved, the DAO Multisig `arb1:0xaF23DC5983230E9eEAf93280e312e57539D098D0` will interact with the Authorizer `0xA331D84eC860Bf466b4CdCcFb4aC09a1B43F3aE6` and call `grantRoles` with the following arguments: > > Roles: `[0x80d8e99e3b5fd50648b67ce84571603afc8ed8ea28310c743deef793d7a98d00,0x6213e9042b9814b9567bde72d3c7a61372862c3ac88c2df77d3205221af6c871,0xbe1515c6c371fbc1aead7b0ed2f23f3bc176eb727e587494ac0055414c5b4c11,0xe4ae7db31fa76b12846f2837e5b8ee34891b1b170470345521a088bd662e4571,0x79cf7f42fcb330293c1d98b9ac2db3a3122a615e3630596ebc2584c6bf0d1346,0xcf5e03a737e4f5ba6d13e23f893a1e0255b362d8ce22e9568e1565fcf92789c7,0xdee20d81c6075dcc437dbaaf02d316ab255cfcae4a154e04b17abdebc70a5b48,0x92253d002d63e0211f775527924e2891f18bb060ff2ab3be19c6b242bafa5fec,0xc383be2c6e87a9b18ae919e677f011279a8d98346dbcd5cb326053f5f873b753,0x70368640683195889d0f146ab060210f43fbb1c317a87bdf17a4dca8d8feed86,0x50ccb689033ea83f58a1b54b091916255bb56c2334a12ed908ecb06f72d2a688]` > > > **Which correspond to the roles for calling \`setSwapFeePercentage\` on the following pool factories** > > > > WeightedPool v1 > > > > WeightedPool2TokensFactory > > > > Stable Pool v1 > > > > Stable Pool v2 > > > > ComposableStablePool > > > > WeightedPool v2 > > > > ComposableStablePool v2 > > > > WeightedPool v3 > > > > ComposableStablePool v3 > > > > WeightedPool v4 > > > > ComposableStablePool v4 > > Account: `0xad3b67bca8935cb510c8d18bd45f0b94f54a968f` > > Which corresponds to the address for 1inch Labs’ Fusion resolver. ---

Hazzuh, love to see further progression on this front. Very much interested in seeing the results of these permissions being granted. Hope we are able to monitor the effects of this real time, L2s will be a huge impact. In favor . 🙂 ---

I am also curious to see the results of this change (combined with the similar cowswap adjustment). Hopefully this brings better opportunities for swappers and more utilization of Balancer for good flow. ---
